Winter continues, the Institute of Biometeorology CNR provides frost

me to do a lot of cool if they had realized, but perhaps not all the warmth of spring to imagine that there even had to wait until April. To give the cold is the story of Florence's Institute of Biometeorology National Research Council, CNR-Ibimet with a study that analyzed the current climate and weather during February-March 2010. According to the monthly and seasonal forecasting system developed by the Institute over the past three years, there will be a busy during the winter that will last well into March. This painting estimate, based on climatic indices tropospheric and oceanic expected negative anomalies of temperature at high altitude for the next two months.

Meteorologists of the National Research Council stated that "the winter of this year was characterized by 'Minor Warming '- that is an anomaly in the stratosphere - just before the middle of December, which resulted in some phases of the circulation in the troposphere zonal block until the middle of January about. " This event has caused, in addition to the waves of intense cold over most of central North America and Asia, including the snowy period on Italy before Christmas. Currently the stratospheric polar vortex would be extremely weakened and moved towards northern Europe. Researchers dell'Ibimet-CNR report, in fact, a "Minor Warming during the last week of January and a 'Geoalert' - ie stratospheric warming over thirty degrees centigrade in seven days - provided the first week of February. " In particular, they explain from Florence, the latter anomaly could result in the degree of 'Major Warming', "an irregularity in the stratosphere with a reversal of atmospheric circulation and the subsequent formation of a cyclonic structure in the vicinity of the pole, where he normally resides a vortex cyclone. "

Our peninsula could therefore be affected by descents of cold air masses of both maritime and continental polar origin as early as next week. Initially they should be polar maritime origin and probably after the first ten days of February, the air masses still very dry and cold of Siberian origin. "The stratospheric anomalies are observed such" dall'Ibimet say, "you can imagine, our country, with significant negative abnormal heat down the cold air not only in the month of February, but also in that of March."

Regarding the forecast for the next two months, are expected values \u200b\u200bof thermal anomaly typical of this type of events: about -1 degrees Celsius over the entire two months. Currently, the bulk of the planned thermal anomaly seems to be centered on Eastern Europe. Perhaps, then, the Italian regions most vulnerable will be those northern and central Adriatic. Dall'Ibimet Giampiero Maracchi speaks of an "anomalous cloud cover in the Northern Hemisphere of the planet" that could be one explanation for this temperature. The researcher says that "the same global warming in some situations can cause anomalies in atmospheric circulation." At the level of the northern hemisphere, there has been an anomaly of cloudiness, "said Maracchi. "In this case the clouds intercept solar radiation and tend to cool the soil surface, and this is an interpretation, albeit partial, of the persistence of the cold."
