Answer:Polar climate precipitation is the average temperature of the warmest month at less than 10 degrees celsius (50 degrees celsius).
Explanation:Polar climate regions are characterized by lack of warm summers.Polar climates tends to be extremely dry since the descending cold air does not have a significant amount of moisture.The two polar regions are usually identified as key regions for monitoring global change,because the surface air temperature and precipitation is expected to increase especially rapid in these two regions along with the ongoing increase of atmospheric carbon dioxide.
