Abstract
In recent years, some volcanic eruptions have focused scientists’ attention on the detection and monitoring of volcanic clouds, as their impact on the air traffic control system has been unprecedented. In 2010, the Eyjafjallajökull eruption forced the disruption of the airspace of several countries, generating one of the largest air traffic shutdowns ever. Extreme convective events cause many deaths and injuries, and much damage to property every year, accounting for major economic damages related to natural disasters in several countries. Due to global warming, Atlantic tropical cyclones have increased their maximum intensity, hurricanes have more often become extratropical cyclones affecting northern Europe, and southeastern Europe is characterized by increasing annual stormy days. Convective and Volcanic Clouds (CVC) are very dangerous for aviation operations, as they can affect aircraft safety and economic, political, and cultural activities. The detection, nowcasting, and monitoring of CVC is therefore vital for organizing efficient early warning systems.
Highlights
The aim of this Special Issue is to collect innovative techniques to detect and nowcast Convective and Volcanic Clouds (CVC) and to create a solid background to be used by modelers and forecasters
The Special Issue includes three papers [1,2,3] reporting new techniques to detect volcanic cloud top heights: two papers focusing on the Etna eruptions [3,4] and one paper [5] showing a new function to nowcast extreme weather events on the European area with the highest frequency of strong convection
The radio occultation is able to sound the atmosphere with a high vertical resolution, and it is sensitive to the atmospheric density variation due to the presence of the cloud
