How Do Geographers Distinguish Between The Types Of Dry Climate?

Dry climates are among the most common climates on Earth. They are characterized by low precipitation, high temperatures, and a lack of humidity. Geographers differentiate between the types of dry climates by examining the amount of precipitation, the temperature range, and the humidity levels.

Amount of Precipitation

The amount of precipitation is the most important factor in distinguishing between the different types of dry climate. Arid climates are the most extreme, receiving no more than 10 inches of precipitation each year. Semi-arid climates receive between 10 and 20 inches annually, while hyper-arid climates receive less than 4 inches.

Temperature Range

The temperature range is another key factor for distinguishing between the different types of dry climate. Arid climates have the highest temperatures, with summer highs exceeding 90 degrees Fahrenheit. Semi-arid climates have slightly cooler temperatures, with summer highs typically between 85 and 90 degrees. Hyper-arid climates are the coolest, with summer highs typically between 75 and 85 degrees.

Humidity Levels

The humidity levels in each type of dry climate can also be used to differentiate between them. Arid climates have the highest levels of humidity, typically between 25 and 35 percent. Semi-arid climates have slightly lower levels, typically between 10 and 25 percent. Hyper-arid climates have the lowest levels of humidity, typically between 5 and 10 percent.

Conclusion

Geographers distinguish between the different types of dry climates by examining the amount of precipitation, the temperature range, and the humidity levels. Arid climates are the driest, receiving no more than 10 inches of precipitation each year and having the highest temperatures and humidity levels. Semi-arid climates are slightly cooler and receive between 10 and 20 inches of precipitation annually. Hyper-arid climates are the coolest and have the lowest levels of humidity, receiving less than 4 inches of precipitation each year.
