WHAT IS WEATHER?
Weather is the state of the atmosphere at a given time and place, with respect to variables such as temperature, humidity, wind velocity, and barometric pressure.Temperature is the degree of hotness or coldness of the environment.
Humidity is the wetness that can be felt either as a vapor in the atmosphere or as a liquid on the ground.
Wind is the movement of air from any of the four points on the compass.
Barometric pressure is the amount of atmospheric pressure placed on land, and the measurement is used in assisting judgement of probable weather changes.
Normal Weather in California for the Month of February
With such a large and diverse land area as California, the climate is varied. The climate along the coast is mild, and cooler along the central and northern coast. Southeastern California is hot and dry. Most of California is marked by only two distinct seasons; a rainy season and a dry season. The rainy season runs from October to April in northern California and from November to March or April in southern California.In a normal year, California’s wet season is still going strong in February. The storms occur in families with heavy precipitation occurring especially in the northern and mountain areas. Even dry southern areas get into the swing of things in some storms in most years. Heavy rains in the lower coastal and valley locations give way to very heavy snows in the mountains. The snow in the mountains left after a strong Pacific storm is measured in feet. After these stormy spells, periods of pleasant even warm winter weather are common. When the Great Basin high builds, the Santa Ana winds can blow bringing warm, dry weather to southern and sometimes central areas.
