Question

Could a desert form at 45°N latitude

Answer 1

Deserts tend to form around 30 latitude because that region is the subtropics where they experience high air pressure so clouds won't form and there would be very little or no precipitation and because it is far inland so far away from bodies of water so to answer your question no probability not

Answer 2

Yes

Step-by-step explanation:

Some deserts are formed due to the movement of hot air masses and the lack of moisture from the tropics, influenced by the Earth's rotation. These masses, after cooling in the atmosphere and curving north and south, begin to lose latitude up to approximately 30 °, however, they gain heat from the descent by increasing their ability to retain and "absorb" the available water in the soil. These deserts are between 30 ° to 50 ° (north / south). Examples are the Sahara Desert in Africa and Soonora in North America.
