Abstract: Rangelands dominate arid and semi-arid lands of the Greater Horn of Africa (GHA) region, whereby pastoralism being the primary source of livelihood. The pastoral livelihood is affected by the seasonal variability of pasture and water resources. This research sought to design a grid-based forage monitoring and prediction model for the cross-border areas of the GHA region. A technique known as Geographically Weighted Regression was used in...

Abstract: An attempt has been made in the present study to forecast fog with a diagnostic method using the outputs of global NWP model. The diagnostic method is based on the combination of thresholds of meteorological variables involved in fog formation. The thresholds are computed using the observations during fog. These thresholds are applied to the output of a global NWP model for forecasting fog. The occurrence of fog is a common phenomenon during... More

Abstract: Indoor air pollution in buildings puts people at risk of developing respiratory and cardiovascular diseases. Particulate matter (PM) exposure is known to cause these health issues. Preliminary efforts were made in this study to assess the quantity and quality of PM1.0, PM2.5, and PM10 present in an abattoir and a residential building in northern Nigeria. Canree A1 low-cost sensor was used to monitor the locations, 8 hourly for two weeks. The... More

Abstract: Here the authors examine whether bell sounds can have an impact on ambient aerosol levels and size distribution under atmospheric conditions. The authors present calculation results for acoustic the coagulation by church bell sounds for a range of ambient aerosol types. The results show that for orthokinetic sonic agglomeration, while the frequency spectrum of church bells is ideal for causing coagulation of ambient aerosols, the sound pressure... More

Abstract: An attempt has been made in the present research to simulate a deadly flash-flood event over the City of Skopje, Macedonia on 6 August 2016. A cloud model ensemble forecast method is developed to simulate a super-cell storm's initiation and evolutionary features. Sounding data are generated using an ensemble approach, that utilizes a triple-nested WRF model. A three-dimensional (3-D) convective cloud model (CCM) with a very fine horizontal grid... More
