Final answer:
Desert weather is known as an arid climate, with low precipitation, high daytime temperatures, and cooler night time temperatures.
Step-by-step explanation:
The desert weather is known as an arid climate, which is characterized by very low precipitation and often experiences high temperatures during the day and considerably cooler temperatures at night. Deserts are typically found in regions where there are conditions such as high-pressure systems that prevent cloud formation or the rain shadow effect where mountains block the passage of rain-producing weather systems. Examples of arid climates include the Sahara Desert in northern Africa and the Mojave and Sonoran Deserts in North America. These areas typically have low annual precipitation and the rate of evaporation typically exceeds the rate of precipitation.
