Christian Eide and team: DYEIII - forecast 3 Sep - day 3
Posted in Christian Eide | By Marc |
This satellite image is taken from the noaa19 - AVHRR radiometer early this morning. It shows the Western and Southern parts of Greenland still in the dark while daylight is present over the North and East. Nevertheless this picture shows well the extension of the frontal system that covers the Eastern parts of Greenland. This system originates from the ex-tropical cyclone Danielle.

Forecast Dye III - 03 September 2010 - day 3
Position: N65.138 W-43.82
Altitude: 2490meter
Quick update
General:
The frontal system has reactivated by the warm air introduced by the Ex tropical cyclone Danielle (you would not expect this in Greenland but in the world of weather systems everything is possible); Such a system is very hard to handle by the meteorological models, so the forecast can change very quickly. What happened with the last run.
The latest satellite image of Greenland reveals the presence of that big weather system over the main parts of Greenland, and this is not likely to clear within the first 48 hours. So the expected improvement for tomorrow is slightly delayed.
