When a warm air mass meets a cold air mass, they don't mix as they have different densities (a bit like oil and water). Instead, the warm less dense air is pushed up over the cold dense air creating the 'front'. Convective rain, or showery precipitation, occurs from convective clouds (e.g., cumulonimbus or cumulus congestus). It falls as showers with rapidly changing intensity. Convective precipitation falls over a certain area for a relatively short time, as convective clouds have limited horizontal extent. Describe how does precipitation occur and what determines the type of precipitation that falls to Earth? Precipitation occurs due to the immense collection of water vapor in the form of clouds. When the water vapor in these clouds gets too heavy, it falls. Rainfall intensity is classified according to the rate of precipitation: 1 Light rain when the precipitation rate is < 2.5 mm (0.098 in) per hour. 2 Moderate rain when the precipitation rate is between 2.5 mm (0.098 in) - 7.6 mm (0.30 in) or 10 mm (0.39 in) per hour. Rain & Floods How does rain form? Water droplets form from warm air. As the warm air rises in the sky it cools. Water vapor (invisible water in the air) always exists in our air. Warm air holds quite a bit of water. For example, in the summer it is usually very humid. When enough of these droplets collect together, we see them as clouds. Most of the condensed water in clouds does not fall as precipitation because their fall speed is not large enough to overcome updrafts which support the clouds. For precipitation to happen, first tiny water droplets must condense on even tinier dust, salt, or smoke particles, which act as a nucleus. Precipitation - Measurement. 1 The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in 100 mm (4 in) plastic and 200 mm (8 in) metal varieties. [74] 2 Other types of gauges include the popular wedge gauge (the cheapest rain gauge and most fragile), the tipping bucket rain gauge, and the weighing rain gauge. Query: how does precipitation occurs
A:
Precipitation occurs when cloud droplets combine and grow large enough to fall to the earth the rate of evaporation as a drop falls to the earth also can affect its size.
