Illustrates Western Disturbances (WDs) and describes their structure, migration and dynamics
Details the influence of WDs over India during the different seasons of the Indian annual climatic cycle
Reviews the possible positive and negative impacts of WDs and considers them in the changing climate
This book examines the meteorological phenomenon known as Western Disturbances (WDs) and traces their influence on the Indian subcontinent. It fully details the unique characteristics and dynamics of these disturbances, which produce large-scale instabilities in the atmosphere over northern India due to the orographic influence of the Himalayas.
The authors first present a definition of the phenomenon and then go on to detail their structure and migration. Topics include dynamics, energetics and thermodynamics modelling studies land-use and land-cover interactions and WDs in the changing climate.
In addition, coverage outlines how WDs interact with and influence other weather systems throughout the four seasons of Indian climate: winter, pre-monsoon, monsoon and post-monsoon. It places special emphasis on wintertime dynamics since WDs significantly contribute to the precipitation in India during this time. The authors explain why this period should be termed "Indian winter monsoon" and differentiate it from the northeast monsoon which so far is the prevalent term used in the region's meteorological parlance.
Complete with detailed illustrations and case studies, this monograph will help researchers and students gain a fundamental understanding of these important storms. This knowledge is essential not only for shortterm and seasonal hydrometeorological forecasting but also for the assessment of regional climate change and its impacts.
