Abstract: | Based on the meteorological data over a period of 4 years (1980–3), the macro-environment of BenCat Farm situated in the southern
part of Vietnam (27 m above mean sea-level, 11° N and 106° E) was categorized as a “monsoon tropical climate”, due to heavy
rainfall (annual mean 2028.96 mm) and about 32% wet days (annual mean 116.52 days) together with high air temperature (annual
mean daily temperature 28.58, max. 32.33 and min 24.85° C). April was the hottest (monthly mean >35°C) and January the coldest
month (monthly mean <22° C) of the year. The maximum number of wet days were during September and October (mean 18 days.month),
whereas the minimum number of wet days were during January and February (mean <1 day/month). The months of December and January
at Ben-Cat buffalo farm were categorized as the “comfortable (moderate-Dry) period” as the mean daily temperature was <27°
C, while the remaining 10 months of the Calender year (February–November) were categorized as the “hot period” (mean daily
temperature >27° C). On the basis of rainfall and the number of wet days, the hot period was further subdivided into a “hot-dry
period” (February–April, mean of 1.67 wet days/month and mean rainfall 19.43 mm/month) and a “hot-humid period” (May–November,
mean of 15.57 wet days/month and mean rainfall 276.28 mm/month). |
