For mountain ranges that are subjected to prevailing winds, why is the climate drier on the leeward (downwind) side?

#9. Diversity of Life Forms
  1. Deserts create dry conditions on the leeward side of mountain ranges.

  2. The sun illuminates the leeward side of mountain ranges at a more direct angle, converting to heat energy, which evaporates most of the water present.

  3. Pushed by the prevailing winds on the windward side, air is forced to rise, cool, condense, and drop its precipitation, leaving drier air to descend the leeward side.

  4. Air masses pushed by the prevailing winds are stopped by mountain ranges and the moisture is used up in the stagnant air masses on the leeward side.

The temperature of the body is regulated almost entirely by nervous feedback mechanisms, and almost all these mechanisms operate through temperature regulating centers located in the hypothalamus. Following statements are as follows:
A. The anterior hypothalamic-preoptic area contains large numbers of heat-sensitive neurons, as well as about one third as many cold-sensitive neurons. These neurons are believed to function as temperature sensors for controlling body temperature.
B. The heat-sensitive neurons increase their firing rate 2- to 10-fold in response to a 10°C increase in body temperature. 
C. The cold-sensitive neurons, by contrast, increase their firing rate when the body temperature increases.
D. Anterior hypothalamus integrates the central and peripheral temperature sensory signals.
