Summer in April?
According to the Royal Netherlands Meteorological Institute (KNMI), April 2007 has been the hottest, driest and sunniest April ever recorded. With respect to heat and drought, this month does not fit into the bandwidth of previous April months, in spite of its capricious nature. Global warming has made the high temperatures less unlikely, but the main cause is an extraordinarily persistent high-pressure system that brought dry, sunny and warm weather to a large part of Europe. As this pattern is not predicted to occur more frequently by the current climate models, KNMI attributes it to a chance fluctuation in the weather.
