Numerical Weather Prediction Techniques

Numerical Weather Prediction (NWP) technique uses mathematical models of the atmosphere to predict weather based on current conditions. During the last two decades, weather forecasting all over the world has greatly benefited from NWP models. Significant improvement in accuracy and reliability of NWP products has been driven by sophisticated numerical techniques (advanced data assimilation algorithms, […]

Forecasting Tropical Cyclones

Losses caused by a tropical cyclone (TC) depends on hazard and vulnerability analysis, preparedness and planning, early warning, prevention and mitigation. Early warning is a major component of disaster management in the south Asian region. This involves monitoring and prediction of a cyclone, effective warning and dissemination of relevant information to people, coordination with emergency […]

A Historical Perspective of Tropical Cyclone Research

Tropical cyclones (TCs) occur over the warm tropical oceans of north Atlantic, western North Pacific, eastern North Pacific, northern Indian Ocean (NIO), south Indian Ocean and the south Pacific Ocean. The average combined frequency of occurrences of TCs is about five in a year over the Bay of Bengal (BoB) and the Arabian Sea (AS) […]
