Cloud Top Temperature and Height product of the Nowcasting SAF applied to tropopause-penetrating cold-ring shaped storms

Popis výsledku v původním jazyce

The Cloud Top Temperature and Height product of SAFNWC (Satellite Application Facility on support to Nowcasting and Very Short-Range Forecasting) represents important characteristics of convective storm tops, and is frequently used as an indicator of possible storm?s activity or severity. While this product is quite reliable for a majority of storms, we can anticipate certain problems when the storms are vertically extensive and their cloud tops penetrate high above the tropopause. In such extreme casesnon-adiabatic processes may be involved, forming a cloud top brightness temperature (BT) field, which may not be directly linked to the cloud-top height. The storms exhibiting the cold-U or cold-ring shaped features with warm embedded areas at their cloud tops belong among these cases. Since some of the cold-ring shaped storms are accompanied by a severe weather, proper interpretation of their BT field by the SAFNWC products is essential for any nowcasting applications.
