Multi-Scale Precipitation Variability Over the Tropics: New Insights from Observations and Modelling explores the latest developments in the observation and modelling of tropical precipitation. Researchers will benefit from this detailed analysis of recent advancements in the field. The text first examines recent satellite and RADAR observations and how those breakthroughs enhance our understanding. This is followed by a review of NASA A-train observations as well as extreme events. The editors also look at predicting precipitation variability with a state-of-the-art ensemble forecast system. The text wraps with a discussion of multiscale cloud and precipitation variability with the backdrop of a changing climate.This text will provide researchers with new insights and a deeper understanding of the latest advances in the observation and modelling of tropical precipitation.

This book is a survey of the research work done by the author over the last 15 years, in collaboration with various eminent mathematicians and climate scientists on the subject of tropical convection and convectively coupled waves. In the areas of climate modelling and climate change science, tropical dynamics and tropical rainfall are among the biggest uncertainties of future projections. This not only puts at risk billions of human beings who populate the tropical continents but it is also of central importance for climate predictions on the global scale. This book aims to introduce the non-expert readers in mathematics and theoretical physics to this fascinating topic in order to attract interest into this difficult and exciting research  area. The general thyme revolves around the use of new deterministic and stochastic multi-cloud models for tropical convection and convectively coupled waves. It draws modelling ideas from various areas of mathematics and physics and used in conjunction with state-of-the-art satellite and in-situ observations and detailed numerical simulations.   After a review of preliminary material on tropical dynamics and moist thermodynamics, including recent discoveries based on satellite observations as well as Markov chains, the book  immerses the reader into the area of models for convection and tropical waves. It begins with basic concepts of linear stability analysis and ends with the  use of these models to improve the state-of-the-art global climate models. The book also contains a fair amount of exercises that makes it suitable as a textbook complement on the subject.
