Hail is a climatic risk which, although rare, can cause natural disasters of large expansion in a short period of time, that are local or regional depending on the trajectory of Cumulonimbus cloud that has generated it. The central part of the country is more subjected to hail falls than the rest of the country. The damages caused annually as a result of hail are on the average only 4-5 percent of all damages determined by weather-related hazards. But, there are spent large amounts of money in order to combat hail in Moldova by active methods that are neither economically nor ecologically justified. In most countries affected by hail are used passive measures and means to combat it, which are ecologic and consist in: delimitating areas affected by this phenomenon and their cultivation with hail resistant plants; covering precious agricultural plantations with net (fruit bearing trees, grapevines, etc.); ensuring agricultural lands against the danger of hail falls etc.
