The first episodes of floods caused by heavy rainfall during the major rainy season in 2018 occurred Accra (5.6°N and 0.17°W), a coastal town, Kumasi (6.72°N 1.6°W) forest region on 18th 28th June, respectively. We applied Weather Research Forecasting (WRF) model to investigate examine meteorological dynamics, which resulted extreme that 14 deaths, 34076 people being displaced with damaged properties, economic loss estimated at $168,289 for two cities according National Disaster Management...
Abstract Periodic climate zoning is an essential classification of land cover to account for anthropogenic activities resulting from population increase and urbanization that affect key response parameters. Rainfall, relative humidity (RH), maximum (T max ) minimum temperature min data the Ghana Meteorological Agency were used zone by adopting cluster PCA analysis methods verifying groupings with seasonal trend Tukey Honestly Significance Difference (HSD) analysis. The grouped synoptic...
The increasing demand of Ghana's renewable energy sector requires a comprehensive evaluation sky conditions that may be favourable for the efficient harnessing solar resources. However, data such are typically scarce due to instrumentation challenges. Empirical estimates using sunshine duration and cloud cover as input were used evaluate resources' potential at 22 synoptic stations distributed across four climatic zones Ghana (savannah, transition, forest coastal) period 2015 – 2018....
Sub-Saharan West Africa is among the regions with highest climate risk, especially semi-arid Sahel region which characteristically a hotspot. The lies at large latitudinal gradient of mean temperature and precipitation. Therefore, even small variations in seasonal meridional migration Intertropical Convergence Zone (ITCZ) lead to drastic hydro-climatic shifts, such as pronounced drought or increased flood risk --- severe socio-economic consequences. Densely populated rapidly growing urban...
The monitoring of rainfall variability over recent decades has become a necessity due to its devastating effects such as floods and droughts, which render humans vulnerable across different parts the West African region. current study seeks provide good understanding within minor season southern Ghana by employing statistical tools quantify in rainfall. Daily data from 1981 2018 for seventeen (17) synoptic weather stations are used this analysis. We perform trend descriptive statistics...
The changing environment, climate, and the increasing manifestation of disasters, has generated an increased demand for accurate timely weather information. This information is provided by National meteorological authorities (NMAs) through different dissemination channels e.g., using radios, Televisions, emails among others. use ICTs to provide recently gaining popularity. A study was conducted in three countries, namely Nigeria, Uganda, South Sudan assess efficiency ICT tool, known as...
Abstract Understanding the environmental evolution of mesoscale convective systems (MCSs) is critical for forecasting weather in West Africa. This study investigated thermodynamic and synoptic environments MCSs over Africa on 26 (storm 1) 28 2) June 2018. Primary datasets used to assess diurnal storms were obtained from ERA5. The results showed a trapped gravity wave, enhanced by well‐established African Easterly Jet monsoon trough, was responsible initiation storm 1. Both also initiated...
Thirteen satellite precipitation products (SPPs), re-gridded to 1 km resolution, were evaluated in terms of the structural similarity index (SSI) over Pra catchment Ghana. Three SPP scenarios considered: Scenario one (S1) was original SPPs; two (S2) bias-corrected and three (S3) better S1 S2 for each wet day. For scenario, best selected constitute 14th referred as BEST SPP. Each SSI against rain gauge rainfield S1, top SPPs TMPA, GSMAP CMORPH; S2, CMORPH, PERCCS MSWEP three; S3, TMPA came...
Rainfall variability has resulted in extreme events like devastating floods and droughts which is the main cause of human vulnerability to precipitation West Africa. Attempts have been made by previous studies understand rainfall over Ghana but these mostly focused on major rainy season April-July, leaving a gap our understanding September-November very important aspect Ghanaian climate system. The current study seeks close this knowledge employing statistical tools quantify variabilities...
Abstract The increasing complexity of West African mesoscale convective systems (MCSs) has signified the need for consistent studies their evolution. Currently, most have focused on wet‐season MCS dynamics, but dry‐season storms are equally important to enhance predictability. Here, two severe thunderstorm case in dry (February 13, 2018) and wet (June 18, seasons were probed understand synoptics, cloud properties, thermodynamic anomalies, kinematic environments. Storm properties analysed...
