Our definition and example will make it clearer. There are many different ways of describing or classifying climates.
Thermal comfort is important for tourists, building designers and people with health concerns.
For these people, a map showing climate zones based on temperature and humidity will be useful. In the K ppen classification scheme, the climate of each region is based on temperature and rainfall, as indicated by the native vegetation. For example, date palms grow only in regions where the mean temperature of the coldest month is greater than 18 degrees C, so K ppen chose the 18 degree C isotherm in the coldest month as the boundary of the equatorial climate. In our dry climate, a map showing climate zones based on rainfall only will be useful for irrigation planners and water supply managers.
