The atmospheric pressure of 1013 hPa is equivalent to 760 mmHg.

Using a dew point calculator or approximation, the dew point at 80% relative humidity and 25°C is approximately 22°C.

Using the formula for dew point, the approximate dew point at 80% humidity and 30°C is around 20°C.

Using the lapse rate of 6.5°C/km, the temperature drop at 3000 meters is 6.5 * 3 = 19.5°C. Therefore, the temperature at 3000 meters is 30°C - 19.5°C = 10.5°C.

The wind direction is named from where it originates, so it is blowing from the North.

The average atmospheric pressure at sea level is defined as 1013.25 millibars.

The average temperature of the Earth is approximately 15°C.

Latitude is the main factor that determines the climate of a region.

The primary source of energy for the Earth's climate system is the Sun.

Climate refers to the average weather conditions in a particular area over a long period, typically 30 years or more.

The boundary between two different air masses is called a front.

A blizzard is characterized by a significant drop in temperature and heavy snowfall, often accompanied by strong winds.

Cumulonimbus clouds are typically associated with thunderstorms.
