The Synoptic Patterns Associated with Spring Widespread Dusty Days in Central and Eastern Saudi Arabia

Atmosphere, 2014
Four synoptic regimes were identified as accompanying the widespread dust in central and eastern Saudi Arabia. The widespread cases of dust were classified based on the value and spread of the aerosol index data from the TOMS aerosol index (TOMS AI ...

Use of self organizing map to identify precipitation patterns and assess their impact on hydrographic basins in Brazil

RBRH, 2022
In this study, we used neural networks known as self-organizing maps (SOMs) to identify clusters of spatial synoptic precipitation patterns. These clusters were compared with the precipitation regime of the ten main hydrographic sub-basins in Brazil ...
