The Province of Mendoza in western Argentina (32 S., 68 deg W.) is one of the most hail prone areas of the world. Losses to agriculture due to hail historically are >10% of total annual agricultural production. The region is known as the "Land of Wine" and the principal crops are grapes plus a large variety of fruit and vegetables (e.g. apples, cherries, peaches, apricots, plums, melons, garlic, tomatoes). The province comprises a diverse territory of mountains, upland areas, and plains. The western border of Mendoza is occupied by the main Andean cordillera, with a number of peaks above 6400m. Climatic conditions are semi-arid, and the annual rainfall for the Capital City Mendoza is 200 mm.
