How is snow formed

 How does snow form?

     Snow is formed within clouds, that is, when temperatures are low, by the adhesion of small ice crystals to each other, then snowflakes are formed that melt at a degree above 0 degrees Celsius in humid air. , to join again.  together and form larger snowflakes, so its weight becomes heavy, enough to allow it to fall to the ground, snow can be defined as drops of water in its solid and crystallized state in the atmosphere that fall to the ground . 

snow conditions

     freezing point

     Snow forms and falls with a minimum amount of moisture in the air, plus the atmospheric temperature reaches the freezing point, which is equal to or less than 0 degrees Celsius, and the ground temperature should not exceed 5 degrees. Celsius until snow forms.  Except that there are some special conditions and factors for their formation, and if these conditions are not available on the earth's surface, these snow crystals will start to melt; Since Earth's temperature is above freezing, this melting would create water vapor that would cool the atmosphere. 

aerial lift

Atmospheric lifting processes occur as a result of the collision of a warm air mass with a cold air mass, and with the presence of some charged particles in moist air, clouds charged with snow crystals are formed, and thus snow falls.  , and the border between the two masses is called the Front, which is the term used in meteorology to predict the weather.

     Lake Effect Snow Phenomenon

Snow is formed as a result of a cold air current passing over warm lake water, which is called the snow lake effect, and therefore warm moisture from the lake is absorbed and then transported out of the lake.  , so that the A charge of cold air is then discharged to form snow, provided the temperature of the air stream is at or below freezing.

     Climate change

Climate change is one of the causes of snow formation, and this is due to global warming. Humidity, and when temperatures drop in some areas when storms occur, large amounts of snow can fall as a result of high humidity from the wind.

     jet streams

Jet streams affect the weather and many processes that occur within the atmosphere, when a relatively warm air mass from the south and laden with moisture meets a cold air mass from the north, and temperatures in the atmosphere drop. to the freezing point. then it will snow
