Total Precipitation

Total precipitation is the combined measure of all precipitation types (convective, stratiform, etc.)

Precipitation Rate

Precipitation rate is a measure of the intensity of rain, freezing rain, snow, and ice pellets.

Convective Precipitation

Convective precipitation occurs when the surface, within a conditionally unstable or moist atmosphere, becomes heated more than its surroundings, leading to significant evaporation. Convective rain, or showery precipitation, 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. In mid-latitudes, convective precipitation is associated with cold fronts (often behind the front), squall lines, and warm fronts in very moist air.

Precipitable Water

Precipitable water is the mass of water in a column of the atmosphere, if all the water in that column were precipitated as rain.

Potential Evaporation Rate

Potential evaporation rate is a measure of the amount of evaporation that would occur if a sufficient water source were available.

Specific Humidity

Specific humidity (or moisture content) is the ratio of the mass of water vapor to the total mass of the moist air parcel. Specific humidity is defined as the ratio of the mass of water vapor in an air parcel to the mass of dry air for the same parcel.
