Precipitation
Fog
-
-
Occurs when the difference between the air temperature and the dew point temperature is less than 2.8 ° C.
-
-
It reduces visibility and significantly affects the flow of traffic, and in cities the creation of smog
Frost
Usually forms on objects like cars, windows, and plants that are outside in air that is saturated
Water vapor, or water in gas form, that becomes solid
-
-
-
-
Dew
Deposit of waterdrops formed at night by the condensation of water vapour from the air onto the surfaces of objects freely exposed to the sky
It forms on clear nights when the air is calm or, preferably, when the wind is light
-
-
Dew forms on clear nights because on such nights freely exposed surfaces lose heat to the sky by radiation
Snow
Covers, permanently or temporarily, about 23 percent of the Earth’s surface
-
Snow forms when the atmospheric temperature is at or below freezing and there is a minimum amount of moisture in the air
-
Hail
-
Most hailstones measure between 5 millimeters and 15 centimeters in diameter, and can be round or jagged
-
-
Hoar
-
-
-
Under atmospheric conditions, frost takes the form of thin crystal needles, ice crystal grains or creates transparent ice
Types of precipitation
Convectional Rainfall
They occur more often over land in summer in the afternoon, and over sea in winter and at night
Above the very heated substrate, the air rises sharply and cools adiabatically, when the temperature drops to dew point, condensation begins
The precipitation that occurs is usually very strong, but it takes up less space and does not fall for long
-
Orographic Rainfall
Occurs when the mass of air, under the influence of general flow, is forced to rise along the mountain slopes, plateaus,
-
-
Frontal Precipitation
-
-
Such precipitation is not strong, but affects large areas
-
Rain
-
Liquid water in the form of droplets that have condensed from atmospheric water vapor and then become heavy enough to fall under gravity.
