2.1. Climate
II. LAND RESOURCES CONDITIONS
Rainfall amount and distribution and mean annual temperature are the most
important climatic elements determining land suitability for agricultural crops. Rainfall
amount and distribution is related with water availability for evapo-transpiration of the
crop. During vegetative growth water requirement is somewhat higher than that
during the flowering and fruit maturing stages. For mango, for example, a few
consecutive dry months (with rainfall of 9 wet months and no dry
months) and B (7-9 wet months and less than two dry months) according to Oldeman
et al. (1979) classification. Rainfall increases towards the western slopes of the Bukit
Barisan, and is particularly heavy in the southern part of the district. In Meulaboh, all
months receive over 200 mm with peaks in April and October. Zone B occupies
between the very wet west coast and the inland plain and large areas on the upper
slopes of the Bukit Barisan. Table 1 presents monthly rainfall and the number of rain
days based on data from Cut Nyak Dien Airport of Nagan Raya.
The annual fluctuation of monthly temperature is small. The difference
between the warmest months (around May and November-December) and the
coldest months (January and June) is less than 2 o C. The major variation in
temperature is related to the elevation above sea level. Table 2 presents monthly
maximum and minimum temperatures for Meulaboh and the vicinity areas.
