acid rain
Rainwater that has an acidity content greater than the postulated natural pH of about 5.6. It is formed when sulfur dioxides and nitrogen oxides, as gases or fine particles in the atmosphere, combine with water vapor and precipitate as sulfuric acid or nitric acid in rain, snow, or fog. The dry forms are acidic gases or particulates.
Backing Winds
Winds which shift in a counterclockwise direction with time at a given location (e.g. from southerly to southeasterly), or change direction in a counterclockwise sense with height (e.g. westerly at the surface but becoming more southerly aloft). The opposite of veering winds. In storm spotting, a backing wind usually refers to the turning of a south or southwest surface wind with time to a more east or southeasterly direction. Backing of the surface wind can increase the potential for tornado development by increasing the directional shear at low levels.
ceiling
The height of the lowest layer of clouds, when the sky is broken or overcast.
dew
Moisture that has condensed on objects near the ground, whose temperatures have fallen to the dew point temperature.
Evaporation
process by which a liquid or solid is changed to a gas; the opposite of condensation
. Fractus
Ragged, detached cloud fragments; same as scud.
gust
A brief sudden increase in wind speed. Generally the duration is less than 20 seconds and the fluctuation greater than 10 mph.
hail
Precipitation in the form of circular or irregular-shaped lumps of ice
Inflow Jets
Local jets of air near the ground flowing inward toward the base of a tornado.
Jet Streak
A local wind speed maximum within a jet stream.
Kelvin Waves
Fluctuations in wind speed at the ocean surface at the Equator result in eastward propagating waves, known as Kelvin Waves. Kelvin Waves cause variations in the depth of the oceanic thermocline, the boundary between warm waters in the upper ocean and cold waters in the deep ocean. They play an important role in monitoring and predicting El Niño episodes.
millibar
A pressure unit of 1000 dynes cm-2, often used for reporting atmospheric pressure where one millibar equals 1 hectopascal (hPA).
Nocturnal
Related to nighttime, or occurring at night.
outflow
Air that flows outward from a thunderstorm.
precipitation
Liquid or solid water molecules that fall from the atmosphere and reach the ground.
rain
Liquid water droplets that fall from the atmosphere, having diameters greater than drizzle
scattered clouds
Sky condition when between 1/10 and 5/10 of the sky is covered.
thermal
Small rising column of air due to surface heating
Updraft
A small-scale current of rising air. If the air is sufficiently moist, then the moisture condenses to become a cumulus cloud or an individual tower of a towering cumulus or Cb.
Veering Winds
Winds which shift in a clockwise direction with time at a given location (e.g., from southerly to westerly), or which change direction in a clockwise sense with height (e.g., southeasterly at the surface turning to southwesterly aloft). The latter example is a form of directional shear which is important for tornado formation. Compare with backing winds.
warm front
A boundary between a warm air mass that is replacing a cooler air mass.
Zonal Flow
Large-scale atmospheric flow in which the east-west component (i.e., latitudinal) is dominant. The accompanying meridional (north-south) component often is weaker than normal. Compare with meridional flow.
