Meteorological #Autumn is over and we can already say that 2022 is still on track to be the warmest and sunniest year in many regions of #Germany, even if it has become a bit gloomier and cooler at the moment.
Neuerung im Bodenfeuchteviewer des @DeutscherWetterdienst:
Ab sofort kann für ausgewählte Stationen der Jahresverlauf der #Bodenfeuchte abgerufen werden. https://www.dwd.de/DE/fachnutzer/landwirtschaft/5_bofeuview/_node.html
Interessant ist dabei aktuell der Vergleich zwischen Ost und West. Während die Bodenfeuchte z. B. in #Berlin-Dahlem so niedrig ist wie seit rund 30 Jahren nicht, hat sie sich am Flughafen #Frankfurt/Main nach extremer #Dürre im #Sommer erholt und liegt nunmehr am oberen Ende der Bandbreite.
The regime trajectories show a pronounced evolution from "blocking" to "negative NAO" in the NAO-BLO space.
It can therefore be assumed that there could be a sign. increased probability of continental cold air advancing as far as C- or even W-#Europe in the medium term.
#Snow extent in the Northern Hemisphere has reached a record maximum! This is mainly due to the snow-rich North Asian region.
This favors the formation of a "cold high" there, which in turn strengthens and possibly prolongs the blocking of the North Atlantic/Eurasian flow pattern.
This was a very thundery day today in the area of the western #Mediterranean. A prominent line of #thunderstorms formed off the #BalearicIslands from the morning hours, which moved southeastward over the archipelago during the day. Per hour up to 5,000 #lightning #strikes and a total of more than 25,000 lightning strikes were registered throughout the day.
The #storms brought heavy rain and gale-force winds.
Hooray! It's #supercellsunday!
Today we are heading to #Dalhart, #Texas. On May 15, we were able to intercept an HP #supercell that had an extremely high #lightning frequency. The CG flashes were striking every second from the shelf cloud towards the ground. Thus, a discharge made it on almost every photo. However, we were constantly on the run from a dusty outflow boundary. In the end it drove us all the way to southwest #Kansas.
In some regions of southwestern #Germany, the meteorological #autumn ends without any #frost. At some stations, this had never been the case before. At the #Mainz-Lerchenberg station, the autumn has been frost-free only twice so far (2002, 2014). The latest first frost occurred in 2002 on December 7. Going by the MOS #forecast, the first frost will occur on December 3 this year, which would be the second latest occurrence.
The blocking situation over northern/northeastern #Europe continues and will even intensify in the medium term. Further wintering is to be expected over Eastern Europe. The anomaly of the 2m temperature of the mean of the IFS-EPS already ranges from -6 to -10 K on a widespread area. However, it is completely unclear how far the cold air can advance to the west, as the position of the blocking high is subject to great uncertainties.
The vertical resolution increase primarily affects the upper troposphere and stratosphere because this turned out to maximize the benefit for the forecast quality.
Likewise, the horizontal resolution upgrade is restricted to the EPS because it currently operates in a resolution range where an increase immediately results in a better forecast quality, whereas the potential benefit in the deterministic system would be much smaller.
It's going to be a wild Tuesday in the western/central Mediterranean. The #storm, named #DENISE by the Southwest Group of the European Storm Coordination Team, will bring #gale-force winds (gusts up to 10 Bft (100 km/h), locally up to 12 Bft (130 km/h), as well as heavy #rain (locally >30 mm/3 h, accumulated widespread 80 to 140 mm, in the mountains even more). In the higher mountainous areas, heavy #snowfall and gales will partly create #blizzard conditions.
Today I want to start with my highlight of this year, the LP #supercell from May 14, taken not far from "Twister"-#Wakita, #Oklahoma. Just in time for the blue hour, this isolated cell unfolded its full beauty and gave us an unforgettable moment.
