About The Book

Description

The present Met Monograph on NE monsoon contains detailed information on various meteorological aspects viz. mean temperatures, sea level pressure, upper air circulation features, monthly and seasonal rainfall, heavy rainfall, extreme winds, characteristics of monsoon clouds, thunderstorms and lightning, variability of NE monsoon from diurnal, synoptic, intra-seasonal and seasonal time scale and synoptic systems affecting south peninsula and Sri Lanka including the forecasting aspects. | am sure that the present publication with latest information would be very useful for operational forecasters, students and young researchers as an excellent reference book. | also feel that the methodology discussed in the Monograph helpful in addressing climate change issues with the ultimate aim to achieve sustainability.

Key Features

1. Understanding on diurnal, intra-seasonal, seasonal variability, monsoon onset, synoptic weather systems.
2. capability of making more accurate forecasts using the state-of-the-art dynamical models.
3. The details of synoptic systems affecting south peninsula and Sri Lanka.
4. forecasting aspects of these weather systems are also discussed.
5. A brief summary of the verification of forecasts of NE monsoon rainfall over India using two different weather prediction systems.
