Term for a climatic period of prolonged drought caused by no or very little precipitation (rain). A special form is winter drought, which is caused by prolonged frost. The complex interrelationships between soil water supply, air temperature, humidity and the associated overall water balance are important for assessing the negative impact on viticulture. This also depends on many other factors. See Vegetation type (predominant plant species in a particular geographical area) and Viticultural suitability (suitability of an area for quality viticulture).
There is a vast number of sources on the web where one can acquire knowledge about wine. But none has the scope, timeliness and accuracy of the information in the encyclopaedia at wein.plus. I use it regularly and rely on it.
