The maximum temperatures show that the total amount of heat received
on the desert, as compared to that received in the climatic provinces
nearer the sea, is not only great, but also that the amount is
variable on the desert itself, one station receiving much more
heat at certain times of the year than another station. The total
heat for each station is arrived at by adding up the daily maxima
for the midseasonal months, January, April, July, and October, and
dividing by the number of years whose records were consulted. The
amounts given in table 11 are the averages for three to four years,
for three desert stations and for one station in the Tell.
