Figure 2. Climate and malaria suitability data for the Kericho
area from the global gridded climatology data, including
meteorologic and malaria suitability time series. Minimum
(bottom), mean (middle) and maximum (top) monthly temperature
(a) total monthly precipitation (b) and mean vapor pressure (c)
are all plotted with a 25-point (month) moving average (bold) to
show the overall movement in the data. The number of months per
year suitable for malaria transmission (d) are also plotted.
Suitability was determined if rainfall exceeded 152 mm and
temperature exceeded 15°C in any month (1,4). The significance
of these movements is presented in Table.
