während bei uns nichts Aussergwöhnliches passiert, scheint die Situation in den USA ziemlich speziell zu sein. Habe gerade ein E-Mail von meinem Kollegen aus Detroit bekommen, das ich Euch, vor allem auch den Stormchasern, nicht vorenthalten möchte. Paul Gross ist Meteorologe und weatherankor bei WDIV-TV in Detroit. Hier ein Aussschnitt aus seinem Mail:
"... We have had a most extraordinary weather event here in Detroit. First,
of all, we had very little precipitation in April, which is highly
unusual for spring here. In fact, our 0.69 inches of total
precipitation (1.75 cm) made it our fourth driest April ever in Detroit.
Then came a drastic change in our weather pattern:
For the past three weeks, we have a strong jet stream coming across the
northern United States, and this jet has hardly changed during this
time. As a result, a front that separates extremely warm and humid air
to our south from cool and dry air to the north has stayed in our area.
One day, the warm front comes north. Then, a day or two later, a low
pressure area moves through, which brings the front south as a cold
front. Then the warm front comes back north the next day. This
oscillating front has now given us 7.92 (20 cm) inches of rain in the
past three weeks, which makes this month Detroit's second wettest May
ever. And, with more heavy rain coming tomorrow, we will set the record
for most rain ever in May -- and we will still have one week left to go
in the month. It is incredible to go from our 4th driest April to our
wettest May ever. I have never before seen this drastic of a long term
change in our local weather pattern.
Obviously, we have had tremendous flooding here. We have also had very
severe storms. To put this in perspective, we average 6.5 tornadoes in
an ENTIRE YEAR here in the Detroit area. So far THIS MONTH, we have had
nine or ten (I am still waiting for confirmation from our Met Service
about last night's storms). The attached incredible lightning
photograph was e-mailed to me this morning from one of my channel's
viewers.
It has obviously been a very difficult time for us meteorologists, and I
cannot remember the last time I was able to sleep for more than four or
five hours. [...]
