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.
The raindrop size distribution (DSD), or granulometry of rain, is the distribution of the number of raindrops according to their diameter (D).Three processes account for the formation of drops: water vapor condensation, accumulation of small drops on large drops and collisions between sizes.
They are texture, form, line, color, value, and shape. Perspective – the principle of creating the illusion of 3-dimensionality on a 2-dimensional source such as paper. This is achieved by using one or more vanishing points (Line perspective), or making the atmosphere greyer, blurrier and smaller as it goes further back (Atmospheric perspective).
A storm seen at the Baltic Sea near the island of Öland, Sweden.. A storm is any disturbed state of the natural environment or the atmosphere of an astronomical body. [citation needed] It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning (a thunderstorm), heavy precipitation (snowstorm, rainstorm), heavy freezing rain ...
The intensity of the radar echoes (reflectivity) is proportional to the form (water or ice) of the precipitation and its diameter. In fact, rain has much stronger reflective power than snow, but its diameter is much smaller. So, the reflectivity of rain coming from melted snow is only slightly higher.
Standard National Oceanic and Atmospheric Administration rain gauge. A rain gauge (also known as udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation in a predefined area, over a set period of time.

Ice pellets form when a layer of above-freezing air exists with sub-freezing air both above and below. This causes the partial or complete melting of any snowflakes falling through the warm layer. As they fall back into the sub-freezing layer closer to the surface, they re-freeze into ice pellets.
Ice pellets form when a layer of above-freezing air is located between 1,500 and 3,000 meters (5,000 and 10,000 ft) above the ground, with sub-freezing air both above and below it. This causes the partial or complete melting of any snowflakes falling through the warm layer (the French term for sleet, neige fondue , literally means "melted snow ...
