Cold drop
A cold drop (from the Spanish "gota fría") is a term used in Spain that has commonly come to refer to any high impact rainfall events occurring in the autumn along the Spanish Mediterranean coast.[1] In Europe, cold drops belong to the characteristics of the Mediterranean climate.[2][3] It is also termed a cut-off low.
Occurrence
Spain
If a sudden cut off in the stream takes place (particularly in the
flash floods. For instance, the great Valencia flood of 1957
was the result of a 3-day-long cold drop.
This phenomenon is associated with extremely violent downpours and storms, but not always accompanied by significant rainfall. For this, high atmospheric instability in the lower air layers needs to combine with a significant amount of moisture.[4]
Other areas
Cut-off lows are apparent near the
North Pacific, Northeastern United States
and the northeast Atlantic.
