IPMA informs that the scientific article ‘Forecasting Cumulonimbus Clouds: Evaluation of New Operational Convective Index Using Lightning and Precipitation Data’ was recently published by Margarida Belo-Pereira, a researcher at the Institute's Aeronautical Meteorology Division.
The article was published in the journal ‘Remote Sensing’ and aims to present the design and evaluate the performance of a new index with the aim of forecasting clouds of the ‘Cumulonimbus’ type, which involved an evaluation period of two years (January 2022 to December 2023). This index is currently used operationally at the IPMA's Meteorological Forecasting and Surveillance Centre for Aeronautics.
Cumulonimbus clouds can cause lightning, strong winds, heavy precipitation, hail, severe turbulence and the formation of ice on aircraft during flight. In certain circumstances, they can also lead to tornadoes and/or waterspouts. As such, they can jeopardise lives and property and constitute a danger to aviation. This article presents the design of a new index aimed at forecasting Cumulonimbus.
