THE HAIL PHENOMENON IN THE B RLAD DRAINAGE BASIN - SOME ASPECTS REGARDING GENESIS AND DIURNAL FREQUENCY

As a phenomenon whose maximum frequency is achieved in the warm season of the year, hail takes by surprise cereal crops, vegetables and herbs, vine and fruit trees in various stages of development, affecting or stopping the development of their vegetative cycle. A single case of hail, in a critical development phase of the plant can lead to total damage of the year crop. Hail is a phenomenon that must be taken into consideration in the normal course of activity in various fields, when one plans an outdoor work, especially in agriculture, where the cultivated species and their vegetation period are subjected to hail. Sometimes, the hail phenomenon can be less serious, if it occurs at the end of the growing phase of the plant, when the size of the hailstones is small, their density per square meter and the duration of the hail falls are each reduced. Hail’s only positive effect is the precipitation input brought on the active surface, input that it is not known, as it is measured together with the rain, but which adds extra water, often necessary during periods of drought in the area of Barlad drainage basin
