Food security assessment in sub-Saharan Africa requires simultaneous consideration of multiple socio-economic and environmental variables. Early identification of populations at risk enables timely and appropriate action. Since large and widely dispersed populations depend on rainfed agriculture and pastoralism, climate monitoring and forecasting are important inputs to food security analysis. ...

Spatial and temporal rainfall variability analysis at a basin scale is essential to understand water availability for sustainable resource management. This study investigated the spatial distribution trend in Tekeze river using daily data collected from 43 meteorological stations with records 1960 2019. Coefficient of variation, seasonality index (SI) were used evaluate monthly, seasonal annual...

Meteorological parameters play a significant role in affecting ambient air quality of an urban environment. As Dhaka, the capital city of Bangladesh, is one of the air pollution hotspot among the megacities in the world, however the potential meteorological influences on criteria air pollutants for this megacity are remained less studied. The objectives of this research were to examine the rela...

This study investigates the relationship between large-scale climate variability, rainfall oxygen isotopic composition (δO), and cave dripwater δO at Gunung Mulu and Gunung Buda National Parks in northern Borneo (4°N, 115°E) on intraseasonal to interannual timescales. A 3-yr timeseries of rainfall δO contains prominent seasonal and interannual variability. The seasonal cycle in rainfall δO is d...

Streamflow is an important factor in the study of water resource management, floods, and droughts. Dramatic climate change has created extreme rainfall distributions, making the study of streamflow trends and variability even more crucial. In this study, the long-term streamflow data and trends recorded at gauging stations in Northern Taiwan are analyzed using the Mann-Kendall test. The data us...

Network fade countermeasures for link budget can be better implemented based on the knowledge of seasonal variability of rainfall attenuation in a locality. Therefore, in this study, a seasonal approach is applied to estimate the effects of spatial rainfall attenuation in Durban (29◦52’S, 30◦58’E), South Africa using twoyear rainfall data obtained from the RD-80 Joss-Waldvogel (J-W) distrometer...

India's agricultural output, economy, and societal well-being are strappingly dependent on the stability of summer monsoon rainfall, its variability and extremes. Spatial aggregate of intensity and frequency of extreme rainfall events over Central India are significantly increasing, while at local scale they are spatially non-uniform with increasing spatial variability. The reasons behind such ...

There are quite a number of conflicting conclusions about inter-annual trends of the monsoon rainfall over South Asia as a result of global warming. Western Ghats, next to Himalayas are the principal watershed areas for the rivers of India. In this study, an attempt has been made to understand the inter-seasonal and inter-annual patterns rainfall over Agumbe – popularly known as the Cheerapunji...

The amount and annual distribution of rainfall caused a major socioeconomic environmental problem where rainfed agriculture is predominant. This study assessed the long-term variability trends in Wabi Shebele River Basin (WSRB), Ethiopia. basin was discretized into 9 local agroclimatic zones (ACZ) based on elevation. coefficient variation (CV) used to check while modified Mann-Kendall (MK) Inno...
