Most rain forests are located near the equator where the rising air carries a great deal of moisture into the atmosphere, causing rain showers. In the desert regions air is usually sinking so has little humidity except during the rainy season.
Temperatures vary greatly between night and day in many desert regions. Typically, humidity blocks the sun's radiation. Since deserts have little to no humidity, about twice the radiation is absorbed. At night, a greater amount of heat is lost due lack of humidity. This can bring temperatures well below freezing, especially during the winter months.
There are about two dozen major desert regions in the world and each one has different statistics. Temperatures can range from -128 degrees F. in Antarctica to +134 degrees F. in the Mojave Desert
The river basin would generally be more humid.
Temperatures can vary from -135 degrees F in the Antarctic Desert to +134 degrees F in the Mojave Desert.
Deserts generally have low humidity and few clouds. These two factors act to moderate the amount and strength of light hitting the earth. The absence of humidity and clouds also allow any heat stored at the surface of the desert during the day to radiate back into space quite rapidly after the sun goes down. There is no 'blanket' to hold the heat in.
The temperature in the desert can vary widely, with daytime temperatures often exceeding 100°F (37.8°C) but dropping significantly at night. Humidity is typically low in deserts, often below 30%. These conditions result in extreme temperature fluctuations between day and night.
Desert region: characterized by hot temperatures and very low humidity levels. High-altitude areas: typically have lower humidity due to cooler temperatures and thinner air. Polar regions: cold temperatures and dry air result in low humidity levels.
It is not necessarily high. The Gobi Desert is quite cold. Even the American southwest desert gets pretty chilly at night. And - believe it or not - part of Antarctica is a desert. It is the amount of precipitation that makes it a desert, not the temperature.
The desert biome typically has the greatest range of temperatures, with scorching hot temperatures during the day and cold temperatures at night due to low humidity and lack of vegetation to retain heat.
A desert usually has little cloud cover and high humidity that would hold in day time heating. Therefore, the desert cools quite quickly when the sun sets.
The desert climate is characterized by low precipitation, high temperatures, and low humidity due to the lack of moisture in the air. In contrast, the UK has a maritime climate influenced by the ocean, resulting in more moderate temperatures, higher levels of precipitation, and greater humidity. These differences are primarily due to variations in geographical location, proximity to bodies of water, and prevailing wind patterns.
Every desert is different and temperatures depend upon location and season of the year. Temperatures in the Antarctic Desert can drop below -120 degrees F or exceed +120 degrees in parts of the Mojave, Sonoran and Sahara.
This climate is characteristic of a desert climate. During the day, the intense sunlight heats up the land quickly, leading to hot temperatures, while at night the lack of humidity allows this heat to escape, causing cooler temperatures.
To experience fog an area has to have a relative humidity of near or at 100%. The temperatures must be at or near the dew point. Deserts rarely have the humidity levels needed to produce fog.
A desert is a dry, barren place where rain rarely falls and vegetation is limited. These areas typically have extreme temperatures and low humidity levels.
Temperatures vary greatly between night and day in many desert regions. Typically, humidity blocks the sun's radiation. Since deserts have little to no humidity, about twice the radiation is absorbed. At night, a greater amount of heat is lost due lack of humidity.
