Introduction
"Nowcasting starts with an established well-known task of forecasters: Monitoring of the weather. In this lession the weight is on satellite images only and even more restricitve on the most basic satellite material: sequences of IR images.
What I want you to recorgnise and learn is:
1. to get information and security in what can be observed for nowcasting purposes in different weather systems
2.to make a qualitative estimate of Nowcasting
Satellite images contain a lot of weather systems but we will concentrate on three main types: Frontal systems with frontal cloud bands, convective systems with Cbs and MCSs and weather systems with fog and stratus."

"From the material we have seen in the lectures before I got the impression that nowcasting is a forecast for a small area and a very short time period. Convection is a mostly small scale phenomenon and seems predestined for nowcasting procedures. But fronts and sometimes also fog/stratus are synoptic scale systems. How do they fit into this concept of small scale and short time?"
"With nowcasting methods meteorology goes into the small scale in space and time of synoptic scale features. We give answers to the begin of cloudiness and precipitation at a special location, information about strengthening and new developments. In meteorological words we have to look at: advection - change/variability - formation/dissolution of cloudiness. And these are phenomena which can be extracted from sequences of even basic satellite images."
