Work Step by Step
The winds coming from the northeast cool as they rush up the slope of Mt. Waialeale, which condenses the water vapor inside and causes a large amount of precipitation.
This dry air then flows down the mountain toward the southwest. The dry air warms up because the pressure increases. The gas is compressed, having work done on it, which raises its internal energy, which raises the temperature.
The hot, dry air causes the desert-like environment on the lee side of Mt. Waialeale, to the southwest of Kauai.
