Climatic Measurements
The warm season was determined to be between October
1999 and April 2000 and between December 2000
and January 2001, whereas the hot season corresponded
to the May to November 2000 period. The average
ambient temperature and relative humidity for
both periods of the warm season were not different (i.e.,
24.8 vs 25.4°C and 86.5 vs 87.6%, respectively). For
this reason, the two periods were grouped in the same
season in which the average ambient temperature and
relative humidity were 25°C and 86.8%, respectively.
The corresponding values for the hot season were
27.5°C and 83.5%, respectively (Table 1). The proportion
of time when temperature and relative humidity
were above 25°C and 85%, respectively, was higher in
the hot season (26.4 vs 10.9%).
