The fall rate of very small droplets is negligible, hence clouds do not fall out of the sky; precipitation will only occur when these coalesce into larger drops. droplets with different size will have different terminal velocity that cause droplets collision and producing larger droplets, Turbulence will enhance the collision process.

Typical precipitation types associated with a warm front advancing over frigid air Precipitation in the form of a sunshower. In meteorology, the different types of precipitation often include the character, formation, or phase of the precipitation which is falling to ground level. There are three distinct ways that precipitation can occur.
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line. Very commonly, cold fronts have a warm front ahead but with a ...
Sleet and freezing rain occur by a similar process, but are different forms of precipitation. Both are most common in the winter. ... especially if the ground is cold enough for the snow to stick ...
The precipitation can be in the form of rain, sleet or a mixture of wet weather conditions that have saturated the ground saturated deep down. The severity of the cracking of the soil depends on ...
Lake-effect snow is produced as cold winds blow clouds over warm waters. Some key elements are required to form lake-effect precipitation and which determine its characteristics: instability, fetch, wind shear, upstream moisture, upwind lakes, synoptic (large)-scale forcing, orography/topography, and snow or ice cover.
On weather maps, the surface position of the cold front is marked by a blue line with triangles pointing in the direction where cold air travels and it is placed at the leading edge of the cooler air mass. [2] Cold fronts often bring rain, and sometimes heavy thunderstorms as well. Cold fronts can produce sharper and more intense changes in ...
In winter, an inversion can lead to the development of ice pellets and freezing rain. Both these phenomena occur when snow melts in a warm layer aloft and falls into a colder layer near the surface. If the layer of cold air near the surface is thick enough, it will lead to the development of ice pellets as the raindrops re-freeze.
