mgb_phys said:The temperature of a surface in the sun depends on the emissivity (how black) of the surface and the angle to the sun - that's why temperatures are normally quoted 'in the shade'.
The air temperature near the surface is going to be close to the surface temperature.
The extreme maximum temperature for Hot Desert ranges from 43.5 to 49° C.
eha said:I think satellites are measuring the temperature of surfaces of the other deserts regularly, but i can't get to those figures at the moment. Thanks for your interest.
The average temperature of hot deserts is approximately 38°C (100°F), but can reach up to 54°C (129°F) during the day and drop to below freezing at night.
Satellite recordings are used to study hot deserts by providing a comprehensive view of the entire desert region, allowing researchers to track changes in temperature, vegetation, and water sources over time.
The high temperatures in hot deserts are primarily due to the lack of moisture in the air, sparse vegetation, and the reflection of sunlight off of the bare ground and sand.
There is evidence that the temperature in hot deserts is increasing due to climate change. Satellite recordings have shown a trend of rising temperatures in hot desert regions over the past few decades.
Hot deserts play a significant role in shaping global weather patterns. The intense heat and dryness in these regions can create high-pressure systems that can influence the movement of air masses and contribute to regional and global weather patterns.
