What is the Meaning & Cold drop definition
In meteorology is called cold drop to a limited volume of cold air at high atmospheric levels. Meanwhile, in a weather chart (scale of horizontal length of the order of the 1,000 km or more, represents it surrounded isotherms (in a mapping plane, curve joining the points that present the same temperatures in the unit of time considered to be) closed.) Notably, the diameter of the cold drop can range from hundreds to thousands of kilometers, is homogeneous, does not have front lines that separate it from the surrounding masses and has a decisive influence on the time.
Although over the years and advances in the observation of meteorological phenomena, the cold drop concept became outdated and became obsolete for most of the schools of meteorology, in countries such as Spain and Germany, even today, retains a significant presence in the current language.
In the mid-20th century was adopted the new denomination of isolated depression, but, anyway, in popular language follows using the cold drop denomination to refer to that disturbance that can cause tremendous rainfall for hours or days, accompanied by lightning and hail and affecting small surfaces or mid-scale, following unpredictable trajectories that also cause intense winds.
The origin of the phenomenon of the cold drop is especially linked to the Western Mediterranean Sea; during the months of October, when the sea waters are much hotter in relation to continental land, generated important atmospheric instability that ends up generating intense rainfall affecting the nearest coasts. Cold drop will be more important the greater the temperature of sea water, because water vapor amounts as fast and condenses, forming clouds of high altitude immediately.
While the cold drop is most frequent in the middle latitudes, is in the Mediterranean media where achieves greater importance.
Throughout the history of Spain, cold drop has in different parts of the country caused severe disorders by floods which isolated or destroyed whole populations.
