Rapid advection of extremely warm and dry air is studied during two events in
the Mediterranean Basin. On 27 August 2010 a rapid advection of extremely
warm and dry air affected the northeast Iberian Peninsula during a few hours.
At the Barcelona city center, the temperature reached 39.3 ° C,
which is the maximum temperature value recorded during 230 yr of daily
data series. On 23 March 2008 a rapid increase of temperature and drop of
relative humidity were recorded for a few hours in Heraklion (Crete). During
the morning on that day, the recorded temperature reached 34 °C for
several hours on the northern coastline of this island.
According to the World Meteorological Organization none of these events can
be classified as a heat wave, which requires at least two days of abnormally
high temperatures; neither are they a heat burst as defined by the American
Meteorological Society, where abnormal temperatures take place during a few
minutes. For this reason, we suggest naming this type of event flash heat.
By using data from automatic weather stations in the Barcelona and Heraklion
area and WRF mesoscale numerical simulations, these events are analyzed.
Additionally, the primary risks and possible impacts on several fields are
presented. |
