The Pennsylvania State University). In most cases, cumulonimbus clouds are accompanied by showers of rain, snow, or hail. The "omega equation" used in numerical weather models is composed of two terms, the "differential vorticity advection" term and the "thickness advection" term. Recall that dew point temperature is a way to assess the concentration of water vapor present, so low dew points equate to low concentrations of water vapor and high dew points equate to high concentrations of water vapor. It nearly always starts as a funnel cloud and may be accompanied by a loud roaring noise. OVERSHOOTING TOP- A 'bubble' of cloud sticking up above the anvil of a thunderstorm, due to a vigorous updraft within the storm. Cloud Abbreviation in Meteorology. It poses an inordinately high threat to life and property. Snow squalls- brief, intense snow showers, accompanied by strong, gusty winds.
