The potential of instability indices in assessing atmospheric instability is examined for the areas of Attica, Thessaly and Central Aegean and Crete, Greece. Generally, many indices have been developed to estimate the troposphere’s stability for forecasting purposes. At this study several instability indices, commonly used in Meteorology, are computed based on radiosonde data. Firstly, the indi...

Abstract Tropical cyclone genesis indices are valuable tools for studying the relationship between large-scale environmental fields and of tropical cyclones, supporting identification future trends genesis. However, their formulation is generally derived from simple statistical models (e.g., multiple linear regression) not optimised globally. In this paper, we present a framework optimising ind...
