VEGETATION DYNAMICAL PATTERNS RELATED TO RAINFALL VARIABILITY ANALYSED WITH WAVELET COHERENCY FOR SOUTHERN AFRICA
Multi-spectral remote sensing Change detection Environmental monitoring Image interpretation Spatial-temporal Analysis wavelet transformation
2015/12/31
This study contributes to a better understanding of the spatial and temporal patterns of ecosystem dynamics in Southern Africa in response to climatic variability. First, we identified the areas where...
Dynamical Outlines of the Rainfall Variability and the ITCZ Role over the West Sahel
Climate Variability Trend Analysis Empirical SPI BEST Index PDO Index
2013/2/26
This article evaluated the plausible causes of floods and droughts, the relative roles of large-scale climate variability in regional environmental trends, and the prospects for the future of the semi...
Rainfall Variability and Its Impact on Normalized Difference Vegetation Index in Arid and Semi-Arid Lands of Kenya
Semi-Arid NDVI Time Series Southeast Kenya
2013/3/6
Agriculture in arid and semi-arid lands of Kenya is depends on seasonal characteristics of rainfall. This study seeks to distinguish components of regional climate variability, especially El Niño...
Diagnostic statistics of daily rainfall variability in an evolving climate
daily rainfall evolving climate
2010/1/27
To investigate the character of daily rainfall variability under present and future climate described via global warming a suite of diagnostic statistics was used. The rainfall was modeled as a stocha...
Modeling the Effects of Rainfall Variability on Groundwater Recharge in Semi-Arid Tanzania
Rainfall Variability Groundwater Recharge Semi-Arid Tanzania
2009/10/26
A conceptual model of the effects of rainfall variability on groundwater recharge
was developed and applied to a small forested catchment in semi-arid Tanzania.
The model simulated dual-domain recha...
EFFECTS OF RAINFALL VARIABILITY ON SPATIAL ACCUMULATION OF PEAK RUNOFF AND EXCESS RUNOFF DEPTH: LITTLE WASHITA RIVER BASIN, OKLAHOMA, USA
surface runoff components runoff depth peak flow
2009/10/19
This paper demonstrates the spatial variability of surface runoff components, accumulated peak flow (Q a ) and excess runoff depth (R a ), in response to varying distribution of precipitation on a bas...
Orographic effects on convective precipitation and space-time rainfall variability：preliminary results
convective precipitation rainfall
2009/5/18
In the EFFS Project, an attempt has been made to develop a general framework to study the predictability of severe convective rainfall events in the presence of orography. Convective activity is embed...
