average daily precipitation of a hot desert
Desert biomes are the driest of all the biomes. In fact, the most important characteristic of a desert is that it receives very little rainfall. Most deserts receive less than 300 mm a year compared to rainforests, which receive over 2,000 mm. That means that the desert only gets 10 percent of the rain that a rainforest gets! The temperature in the desert can change drastically from day to night because the air is so dry that heat escapes rapidly at night. The daytime temperature averages 38Â°C while in some deserts it can get down to -4Â°C at night. The temperature also varies greatly depending on the location of the desert. Since desert conditions are so severe, the plants that live there need to have adaptations to compensate for the lack of water.
