In the fruit and vegetable product industry, chlorine is commonly used to remove microbes such as bacteria and mold from produce. In the home, a water wash, either with or without the help of a produce brush, is typically used to clean fruits and vegetables.
57 ALPINE ZONE The alpine zone occurs in high mountain areas where the mean annual precipitation is above 41 inches and the RET is the lowest in the state (Figure 7.6). These areas occur above the upper timber line. The vegeta-tion consists mainly of small cushion plants on rocky slopes.
Apart from the three main climate zones, other sub-zones can be found, such as the alpine climate in the Pyrenees and Sierra Nevada, a typical subtropical climate in the Canary Islands and the southern coast and a Hot Arid climate in parts of the South East Coast, notably around Almeria city and the Cabo de Gata region.
