Yes, the source of all clouds and precipitation is water vapor. Water evaporates from bodies of water, such as oceans, lakes, and rivers, and rises into the atmosphere where it cools and condenses to form clouds. When the conditions are right, these clouds release precipitation in the form of rain, snow, sleet, or hail.
Clouds
precipitation
Evaporation form clouds, condensation of vapors from clouds form rains.
It is possible that they could be in a shape of a cloud
Hail
normally cumulus clouds do not produce precipitation. It is cumulonimbus clouds that form rain or snow depending on the season.
Rain is the most common form of precipitation on Earth, consisting of water droplets that fall from clouds.
In solid form: sleet, hail, snow In liquid form: rain, drizzle, fog
Rain is the most common form of precipitation, which includes water falling from clouds in the form of liquid droplets.
In a warm occlusion, clouds and precipitation would form at the boundary where the warm air rises above the cooler air. In a cold occlusion, clouds and precipitation would form along the front where the advancing cold air lifts the warm air. In a stationary occlusion, clouds and precipitation would occur at the boundary between the cool and cold air masses that are not actively moving.
