EUMeTrain: Nowcasting CAL Module - Introduction

There is the extended cloud shield of a big convective cell complex over western and northern parts of Lower Austria.

The superposition of radar shows also extended rainfall areas embedded. The main rain cells are in the southwestern part of the cloud feature but there is also a northern precipitation maximum.

The superposition of lightnings (yellow are those from the last 5 minutes) indicate two maxima of lightnings in the southern parts of the cloud cell while the northern rain maximum shows much weaker lightning activity.

The combination of satellite image, radar echos and lightning events of the last 30 minutes indicate at one glance the convective cell compex and the very active parts within the cloud shield.

The Nowcast of the cloud shield shows an eastward movement of the cloud shield. At this point of time the system is still to the west of the location Mörbisch.

The Nowcast of the cloud shield für the next 2 hours indicates that the eastern edge of the cloud shield just arrives at Mörbisch. However, there is a slight tendency that the coldest part (dark green) has a small norther component of movement leading to the fact that it passes Mörbisch in the north.

The combination of all data sets gives a rather detailed insight in the structure of the convective system.

The Precipitation Nowcast does not shows high rates in the southeastern part; on the contrary this precipitation is ratehr stationary and decreases. The more change is in the more western precipitation pattern which intensifies and moves east-northeastward.

The Precipitation Nowcast does not show high rates in the southeastern part close to Mörbisch; on the contrary this precipitation is rather stationary and decreases. The more change is in the more western precipitation pattern which intensifies and moves east-northeastward; it represents the movement of the convective cell.
