Climate
This entry includes a brief description of typical weather regimes throughout the year; in the World entry only, it includes four subfields that describe climate extremes:
ten driest places on earth (average annual precipitation) describes the annual average precipitation measured in both millimeters and inches for selected countries with climate extremes.
ten wettest places on earth (average annual precipitation) describes the annual average precipitation measured in both millimeters and inches for selected countries with climate extremes.
ten coldest places on earth (lowest average monthly temperature) describes temperature measured in both degrees Celsius and Fahrenheit as well as the month of the year for selected countries with climate extremes.
ten hottest places on earth (highest average monthly temperature) describes the temperature measured both in degrees Celsius and Fahrenheit as well the month of the year for selected countries with climate extremes.
