Nigerian agriculture is mainly rain-fed and basically dependent on the vagaries of weather especially rainfall. Nigeria today has about forty-four (44) observation stations which provide measurement rainfall amount for different locations across country. Hence, this study investigates change detection in pattern over each climatic zone Nigeria. Data were collected 90 years (1910–1999) period all Nigeria, while a subdivision was made to three (3) non-overlapping climate 30 i.e. 1910–1939,...
Abstract There have been increasing losses from freshwater flooding associated with United States (US) landfalling hurricanes in recent years. This study analyses the relationship between sea surface temperature anomalies (SSTA), wind and translation speed North Atlantic tropical cyclone precipitation (TCP) for period 1998-2017. Based on our statistical analysis of observation data, a 1 °C SST increase main development region (MDR), there is 6% (not statistically significant) TCP rate (mmhr...
Satellite derived solar irradiance over 25 locations in the 5 climatic zones of Nigeria (tropical rainforest TRF, Guinea savannah GS, Sahel SHS, Sudan SUS, and Mangrove swamp forest MSF) was analyzed. To justify its use, satellite data tested for goodness agreement with ground measured radiation using 26-year mean monthly daily 16 zones. The well-known R 2 , RMSE, MBE, MPE statistical tests were used good found. grouped into Frequency distribution global done each This showed that 46.88%,...
Abstract The study uses numerical weather prediction models to predict the occurrence of heavy convective rainfall associated with passage African Easterly Wave (AEW) during period 23–26 August 2017 over Nigeria. Fraction skill score (FSS) and method for object‐based diagnostic evaluation (MODE) verification techniques were applied verify how well high‐impact event demonstrate these tools can support operational forecasting. Ensemble model forecasts at a scale from UK Met Office Unified...
Mineral dust over West Africa region modulates summer monsoon through direct radiative forcing. This study examined the impact of mineral forcing on Monsoon variability with aid Regional Climate Model (RegCM4) at 50 km grid resolution driven by ERA Interim re-analysis. Three experiments were performed; first non-dust aerosol version model (CONTROL), and second module (DUST) an increase in concentration (DOUBLE DUST). The simulation was run from October, 2004 to December, 2005 domain 3 months...
Abstract The frequency of flash floods resulting from heavy rainfall over West Africa has increased in recent years with serious socio‐economic consequences. Therefore, the need to utilize numerical weather prediction models forecast events reliably is also rising at many operational meteorological centres Africa. This paper evaluates performance Consortium for Small‐scale Modelling (COSMO) model German Meteorological Services (DWD) predicting high‐impact that occurred between 19 and 26...
This paper identifies fundamental issues which prevent the effective uptake of climate information services in Nigeria. We propose solutions involve extension short-range (1 to 5 days) forecasts beyond that medium-range (7 15 timescales through operational use current forecast data as well improve collaboration and communication with users. Using newly available provide seamless from short-term sub-seasonal timescales, we examine evidence determine if demand-led sub-seasonal-to-seasonal...
<p>The North Atlantic has a major influence on the climate of Europe. In past, decadal prediction systems have shown consistent skill in for initialised models, indicating potential to exploit this better predictions continent. One prime area approach is Ireland, due its proximity Atlantic.</p><p>Until now, island Ireland limited, leading conclusion that dynamical models alone are not able transfer from surrounding land masses. Therefore, project...
<p>Ireland is bordering the North Atlantic, and its climate dominated by modes on short to longer timescales. The Atlantic low-pressure systems, Jetstream variabilities airmasses are features of atmospheric circulation, which also contribute this region.  So, a long-term prediction Ireland majorly controlled ocean, other components.</p><p>The Ocean has shown good capabilities for decadal multi-decadal predictions, hence, our study...
<p>North Atlantic climate variability is dominated by two important subsystems, the Meridional Overturning Circulation (AMOC) and Sub-Polar Gyre (SPG). While AMOC responsible for transport of mass heat into higher latitudes, SPG has been linked with large-scale changes in subpolar marine environment. The strength, intensity positions constituent currents impose variabilities distribution salt North Ocean. Consequently, predictability on decadal scales subsystems huge importance...
