Accra and Kumasi which are the main focus of this study recorded MMR of 180 mm and 215 mm during the peak of the major season, while the peak of the minor season recorded 60 mm and 170 mm, respectively. WRF skew-T diagram showing atmospheric dynamics for case B (a) at 12 UTC and (b) at 18 UTC. 22.09.20 – Second Measuring Campaign in the Pilot Areas in Accra, Ghana 22/09/2020 After the beginning of the rainy season in Ghana and the resulting filling of the natural rainwater retention basins in the pilot regions of Accra, our partner Envaserv started the second measuring campaign. Ghana. One of the reasons for the limited research on extreme rainfall in West Africa is the difficulty in accessing data [31]. II: African easterly waves, convection and rainfall,”, J. Crétat, E. K.

Ghana and Germany are severely restricted by the strict protection measures of their governments. These include studies focusing on dynamics of the West African Monsoon [15] and onset, cessation, and length of rainfall season [16–18]. These conditions ahead of the system supported the westward propagation of the storm, thereby playing significant role in its kinetics. Indeed, above average rainfall amounts relative to the 1981-2010 period are expected over the entire Sahelian strip. It was observed that an appreciable amount of moisture (RH) above 80% at 850 hPa and the 700 hPa was within the atmosphere indicating saturation for storm formation at the 850 hPa levels (Figure 12). Further analysis on the ADMR distribution and frequency over Accra and Kumasi using the normal distribution shows that 68% of the area of the normal distribution for Accra was between 53.03 mm and 136.81 mm of rainfall, which implies that most of the rainfall events occurred within the 1st z-score distribution value, while 95% of the area of the normal distribution was found between 11.14 mm and 178.70 mm of the 2nd z-score distribution value. April to July is classified as the major rainy season and September to November is the minor rainy season. As climate varies geographically, the definition of extreme weather thresholds will also vary. GSMaP satellite products. The model’s configuration setup uses Betts–Miller–Janjic’s [38] convective parameterization scheme for both domains with 49 vertical levels. In addition to the factors identified by Paeth et al. From Figures 12(c) and 12(f), an anticyclonic vortex observed at 200 hPa level, located close to the western border of Mali, ridged over the subregion with weak Tropical Easterlies Jets (TEJ). VoltaBasin.png. 2 WEST AFRICA 2020 SEASON Contents •Short - range forecasts up to 31 th October, marking the end of the season shows continued favorable seasonal conditions in most of the region except some localized pockets of moderate dryness. 2020, Article ID 4230627, 14 pages, 2020. https://doi.org/10.1155/2020/4230627, 1Ghana Meteorological Agency, Accra, Ghana, 2Ghana Space Science and Technology Institute, Ghana Atomic Energy Commission, Kwabenya, Ghana. MMR (1981–2010). The ET extended covering most parts of Niger (excluding the southern fringes and whole of Burkina Faso), northern half of Mali, and eastern Mauritania through to southern half of Algeria. Nigeria. March is not the best month to spend holidays in Ghana. Home; News; Business; Election Bureau; Coronavirus; Showbiz; No Result The study area and data are described in Section 2. This study has shown some of the main synoptic features that produced the heavy rainfall events in Ghana and could serve as a reference for forecasters in Ghana and the West African subregion as far as forecasting heavy rainfall event is concerned. On average, January is the driest month. This condition triggered both zonal and meridional expansions of the ET with the lower portions stretching and covering north (Nigeria, Benin, Togo, Ghana, Ivory Coast, Guinea, and Senegal). Flash floods are frequent across the continent resulting from intense localized thunderstorm activity, slow-moving thunderstorms, or squall lines mostly accompanied by lightning [3]. On the 18th and 28th of June 2018, heavy rains and thunderstorms caused flooding in the two biggest cities in Ghana, resulting in the deaths of 14 people, displacement of 34,076 others, and damaged properties estimated at $168,289 according to the National Disaster Management Organization (NADMO). From the Meteosat Second Generation (MSG) Preparation for Use of MSG in Africa (PUMA) station, MSLP charts at 12 UTC for case A showed that St. Helena had a center value of 1027 hPa, while Azores was 1030 hPa with the equatorial trough (ET) extended zonally to the east of the continent as shown in Figure 10(a). To track the evolution of the rainfall events for this study, the hourly GSMaP images (Figures 2 and 3) were used to track the genesis, development, dissipation, and the active spots of the thunderstorms as they propagated zonally for cases A and B, respectively. At least 18 out of the last 50 years have recorded significant flooding incidences in which lives and properties have been lost [8–11]. Indeed, above average rainfall amounts relative to the 1981-2010 period are expected over the entire Sahelian strip. The spatial distributions of rainfall for the two cases are shown in Figure 4. Thursday, November 26, 2020. COVID-19 and weather/climate nexus Plots (a) and (b) and (c) and (d) for cases A and B, respectively. That’s true for the north. Pls watch this video and answer for your self. This led to its slower movement and subsequent stagnation. Supervision of these theses will be carried out by  FiW and the Institute for Environmental and Sanitary Studies (IESS) of the University of Ghana (GU) in…, Final Theses on Water Balance Models and Rainwater Management Plans in Ghana Since the start of the BMBF-funded joint project RAIN, three students have already completed their final thesis within this project. [37] include evaporation, wetting, wind induced errors, and instrument reading errors on the part of observers. Anthropogenic activities such as buildings on water ways and choked drainage systems were responsible for the floods. The African continent is the second hardest hit by floods in terms of number of events, area affected, and number of people killed after Asia [1, 2]. Possible reasons given for occasional flooding in Ghana include climate variability and change [10, 12] and poor physical planning and flaws in the drainage network [8]. It has been established that low level convergence (i.e., at 925 hPa pressure level) of moisture and upper level divergence are good indicators for large scale precipitation [40, 41]. For best practices globally, [44] established a tasked team on the definition of extreme weather and climate events which classified heavy rainfall threshold greater than 50 mm (>50 mm/24 hr.) The temperature starts rising, especially during the day but the air is very dry.

Pre-rainy season examination; Study your house correctly before the onset of the rainy season. Sign up here as a reviewer to help fast-track new submissions. Ghana is a tropical West African country located between latitudes 4°N to 12°N and longitudes 1.5°E to 3.5°W. The active spot of the storm was centered over Accra, where 212.8 mm of rainfall was recorded leading to flooding over many areas in the city. [. The country's perennially hot climate means that it's always warm enough to don bikinis and board-shorts, and the humidity of the rainy season doesn't matter so much when you're by the sea (or the hotel swimming pool). [32], the occurrence of heavy rainfall also depends on mesoscale and localized convective processes. Datasets used in this study for the evaluation were in situ rainfall data (45 stations), Global Satellite Mapping of Precipitation (GSMaP), Ghana Meteorological Agency (GMet), GMet Weather Research and Forecasting (WRF) model output, and Meteo France Arpege 0.5 mean sea level pressure (MSLP), a product from the Meteosat Second Generation (MSG) Preparation for Use of MSG in Africa (PUMA) project. The storm finally moved westwards from Accra after 06 UTC on the 19th of June, lasting for about 9 hours. So, wind blows them down south and they come here and our rain starts and they have fertile grounds for reproduction… Considering the conditions under which this plague is developing, the likelihood of it getting to Ghana is very high, much higher.” Two hourly precipitation intervals from 12 UTC of the 28th of June 2018 to 02 UTC of the 29th of June 2018 for case B. The northern states of the country, according to him, will experience rainfall from June 22, noting that the respective predicted cessation date for south-south is Dec. 28, while northern parts are Sept. 26. per day. This study investigated the meteorological dynamics for the heavy rainfall that resulted in flood over Kumasi and Accra. Situated just below the Sahara Desert and Sahel, a short rainy season lasts from May to the end of October, bringing the promise of crop cultivation and harvest. This study concludes that the meteorological conditions that aided the formation and propagation of the weather systems that produced the heavy rainfall events resulting in the floods that occurred over the study areas were nonmeteorologically induced. Temperatures in Ghana are expected to continue rising in the future, rainfall in the rainy season and drought in the dry season will increase and cause socio-economic damage. This was observed for the 95th percentile threshold values over Accra and Kumasi. News Ghana is Ghana's leading online news portal for business in West Africa and around the World. Generally, the quasi-static high pressure systems and their consequent effect on the ITB determine the prevailing weather within the West Africa subregion. These characteristics contributed to the development and spread of the convective cells, resulting in the heavy rainfall experienced in Kumasi. Various studies have looked at different aspects of rainfall over the West African region in general and Ghana in particular. 03.07.2020 - Discover intriguing and exciting things to do in Ghana However, the major differences between the two sectors are land cover and topography of the area, which have an influence on the rainfall pattern [37]. In 2012, Nigeria experienced one of the most devastating flooding events ever recorded [7]. Resolutions of 27 km and 9 km (white cell), respectively. Annual rainfall frequency (ARF). Notorious robbers ensured that the 2020/21 Ghana Premier League season got off to an ignominious start after raiding the dressing rooms of both Legon Cities and Berekum Chelsea while the … Remember: The climate in Ghana in march is tolerable across the board. The heavy rainfall events afford us the opportunity to conduct a unique case study focusing on the meteorological explanation of the causes of the event. The south westerly winds filled a cyclonic vortex with speed between 5 and 10 kts (3–5 ms–1) located north of Benin at 12 UTC (Figure 13(a)). Monday December 07 2020. The first episodes of floods caused by heavy rainfall during the major rainy season in 2018 occurred in Accra (5.6°N and 0.17°W), a coastal town, and Kumasi (6.72°N and 1.6°W) in the forest region on the 18th and 28th of June, respectively. Africa and for that matter, Ghana has two major seasons known as dry (harmattan) and wet (rainy) seasons. The harmattan, a dry desert wind, blows in north-east Ghana from December to March, lowering the humidity and causing hotter days and cooler nights in northern part of Ghana. During the rainy season, the country is influenced by the maritime air mass due to the intensification of northward ridging of the St. Helena high-pressure system, which drives moisture into the subregion, while the Azores high-pressure system weakens. BBC, 2007, http://news.bbc.co.uk/1/hi/world/africa/6998651.stm. These play a greater role in causing flood events with moderate rainfall. Location of cases A and B flood events and the distribution of the Ghana Meteorological Agency’s weather observation stations (red dots). Ghana in general, but especially the northern savannah region, is at high risk of flooding, drought and bush fires. The aim of this paper is to document the meteorological conditions that led to the initiation and propagation of the weather systems that caused the heavy precipitation events in Accra and Kumasi by analyzing the synoptic and mesoscale weather charts. It intensified over the middle sector and produced heavy rains lasting for a period of about 8 hours before dissipating at approximately 02 UTC on the 29th of June (Figure 3(f)). Mali. The tropical climate of Ghana is relatively mild for its latitude. On behalf of the Electoral Commission of Ghana, I welcome you to a significant moment in our country’s history: The Declaration of the Results of the 2020 Presidential Elections. The 68% and 95% of the area of normal distribution for cases A and B from annual daily maximum rainfall (mm), respectively. (a) 12 UTC and (b) 18 UTC for case A. Meteo France Arpege 0.5 MSLP charts. This can be attributed to its location along the coast where rich moisture from the Gulf of Guinea fuels thunderstorms development as well as land and sea surface temperature variations producing heavy rainfall [39]. This anomaly could be attributed to seasonal to subseasonal variations. Copyright © 2020 S. O. Ansah et al. In order to avoid some of these errors, wind shielded rain gauges are used by GMet. The umbrella is the main armour for commuters especially those who do not have own vehicles. The first episodes of floods caused by heavy rainfall during the major rainy season in 2018 occurred in Accra (5.6°N and 0.17°W), a coastal town, and Kumasi (6.72°N and 1.6°W) in the forest region on the 18th and 28th of June, respectively. A Great Asset For Ghana Football: Ghanatoday.net. Most rainfall (rainy season) is seen in May and June. B. Omotosho, A. Niger. Results from the analysis showed that surface pressures were low with significant amount of moisture influx aiding the thunderstorms intensification, which produced 90.1 mm and 114.6 mm of rainfall over Accra and Kumasi, respectively. The dew point (blue lines) and the temperature (red lines) profiles showed high levels of humidity (>70%) and temperature profiles of the atmosphere for more cloud formations especially between 925 hPa and 850 hPa where the convective condensation level (CCL) can be estimated. For this purpose, water samples were taken at the end of July from the four permanent water retention areas sampled in the…, Due to the global corona pandemic, many project activities cannot be carried out as planned at present. The rainfall distribution for Kumasi shows that 68% of the area of normal distribution was between 64.37 mm and 108.87 mm, which implies that most rainfalls were within the 1st z-score distribution value. Two domain configurations for GMET’s WRF model. Generally, the month of June is the peak of the major rainy season over southern Ghana. In their work also confirmed that intensive and unplanned human settlements in flood-prone areas played a major role in increasing flood risk in Africa as observed in most parts of Accra (e.g., Avenor and Kaneshie) and Kumasi (e.g., Buokrom and Anloga junction) [6]. The northward and the southward oscillation of the ITB control the rainfall pattern in Ghana where the southern half (below 9°N) of the country experiences bimodal rainfall pattern. Advertisement . It was observed that most rainfalls for the flood events fell below the threshold over Accra and Kumasi (Figure 16). Table 1 summarizes the 1st and 2nd z-score ADMR values over Accra and Kumasi. The weather in Accra, Sekondi-Takoradi, Kumasi, Tema, Mole National Park, Akosombo and Tamale is OK but just acceptable. Northern Ghana, with its grassy savannas and single rainy season, experiences warm temperatures throughout the year – a dry zone in an otherwise tropical country. At 18 UTC, the slow-moving thunderstorm hit the eastern coast of Ghana (Figure 2(d)) and after three hours it had reached Accra as it intensified (Figure 2(e)). Drought. Over 500 lives were also lost and several thousands were forced to migrate to other communities after a 2007 flood event that affected Uganda, Ethiopia, Sudan, Togo, Mali, Niger, and Burkina Faso, which displaced millions of people [5]. The key conclusions from the results and analysis are presented in Section 4. It is worth noting that these records occurred at the peak of the West African Monsoon season over the respective stations. Understanding the dynamics of meteorological conditions and features that influence heavy rainfall will greatly improve extreme weather forecasts and help to mitigate their effect. Sustainable Technologies and Services for Adaptation to Climate Change in Flood- and Drought-Endangered Settlement Areas in Ghana, The content of the BMBF-funded joint project RAIN will be the basis for six final theses, which will be worked on by Ghanaian students on dissertation and master thesis level. The inner domain model products were used. City dwellers occupy riparian zones and wet-lands leading to flood initiation when moderate rains occur. Mechanisms of how the ITB and high pressure systems affect rainfall patterns over West Africa are explained in various literatures [16, 33–36]. The isobar over Ghana ranged between 1010 hPa to the north and 1012 hPa to the south (Figure 11(b)). Accra is one of the most densely populated cities in the country, with high rural-urban migration resulting in unplanned settlements. A. Twumasi and R.

Preko et al., “Variabilities in rainfall onset, cessation and length of rainy season for the various agro-ecological zones of Ghana,”, J. The coast west of Accra is home to beautiful beaches and landmarks including the Elmina and Cape Coast castles. In case B, significant amount of moisture (RH > 80%) was also observed at the 850 hPa and the 700 hPa levels, which reflects the extent of moisture depth within the atmosphere. The upper level jet (200 hPa) was direct easterlies with speed around 35 kts. The average amount of annual precipitation is: 810.0 mm (31.89 in) The results from meteorological analysis indicate that MSLP was low with significant moisture influx for thunderstorm system growth and development. The time series of the ADMR variability (1961–2017) over Accra has a positive slope of 0.45 and Kumasi has a negative slope of –0.07 as shown in Figure 7. Floodis a major hazard and source of human vulnerability which can lead to high mortality rate. A great time to visit Ghana and a tourist high season as well. These studies have identified and explained the roles of key drivers of variability in West African rainfall such as the Madden Julian Oscillation [24], the movement of the intertropical convergence zone [25, 26], the African Easterly Jet and African Easterly Wave [27, 28], and El Niño-Southern Oscillation [29, 30]. Our rainy season (in West Africa) will start. B. Klutse, J. N. A. Aryee, and K. Asare, “Comparison of rainy season onset, cessation and duration for Ghana from RegCM4 and GMet datasets,”, S. S.
