Warm front

Index Warm front

A warm front is a density discontinuity located at the leading edge of a homogeneous warm air mass, and is typically located on the equator-facing edge of an isotherm gradient. [1]

Air mass

In meteorology, an air mass is a volume of air defined by its temperature and water vapor content.

Altocumulus castellanus cloud

In meteorology, Altocumulus Castellanus (ACCAS) is a cloud type named for its tower-like projections that billow upwards from the base of the cloud.

Altocumulus cloud

Altocumulus (From Latin Altus, "high", cumulus, "heaped") is a middle-altitude cloud genus that belongs mainly to the stratocumuliform physical category characterized by globular masses or rolls in layers or patches, the individual elements being larger and darker than those of cirrocumulus and smaller than those of stratocumulus.

Altostratus cloud

Altostratus is a middle altitude cloud genus belonging to the stratiform physical category characterized by a generally uniform gray to bluish-green and sheet or layer.

Cirrocumulus cloud

Cirrocumulus is one of the three main genus-types of high-altitude tropospheric clouds, the other two being cirrus and cirrostratus.

Cirrostratus cloud

Cirrostratus is a high-level, very thin, generally uniform stratiform genus-type of cloud, composed of ice-crystals.

Cirrus cloud

Cirrus (cloud classification symbol: Ci) is a genus of atmospheric cloud generally characterized by thin, wispy strands, giving the type its name from the Latin word cirrus, meaning a ringlet or curling lock of hair.

Cloud

In meteorology, a cloud is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body.

Cold front

A cold front is the leading edge of a cooler mass of air, replacing at ground level a warmer mass of air, which lies within a fairly sharp surface trough of low pressure.

Condensation

Condensation is the change of the physical state of matter from gas phase into liquid phase, and is the reverse of vapourisation.

New!!: Warm front and Condensation · See more »

Cumulonimbus cloud

Cumulonimbus, from the Latin cumulus ("heaped") and nimbus ("rainstorm"), is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents.

Cumulus congestus cloud

Cumulus congestus clouds, also known as towering cumulus, are a form of cumulus cloud that can be based in the low or middle height ranges.

New!!: Warm front and Cumulus congestus cloud · See more »

Density

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.

New!!: Warm front and Density · See more »

Dew point

The dew point is the temperature to which air must be cooled to become saturated with water vapor.

New!!: Warm front and Dew point · See more »

Fog

Fog is a visible aerosol consisting of minute water droplets or ice crystals suspended in the air at or near the Earth's surface.

New!!: Warm front and Fog · See more »

Fractus cloud

Fractus clouds (scuds) are small, ragged cloud fragments that are usually found under an ambient cloud base.

New!!: Warm front and Fractus cloud · See more »

Humidity

Humidity is the amount of water vapor present in the air.

Nimbostratus cloud

Nimbostratus is a stratiform genus formerly classified as "Family C” low-level, but now considered by the World Meteorological Organization (WMO) to be a middle- or multi-level stratus type.

Northern Hemisphere

The Northern Hemisphere is the half of Earth that is north of the Equator.

New!!: Warm front and Northern Hemisphere · See more »

Occluded front

In meteorology, an occluded front is a weather front formed during the process of cyclogenesis when a cold front overtakes a warm front.

New!!: Warm front and Occluded front · See more »

Pseudo-warm front

A pseudo-warm front is a boundary between the in-flow region and the forward-flank downdraft of a supercell.

New!!: Warm front and Pseudo-warm front · See more »

Rain

Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then becomes heavy enough to fall under gravity.

New!!: Warm front and Rain · See more »

Southern Hemisphere

The Southern Hemisphere is the half of Earth that is south of the Equator.

New!!: Warm front and Southern Hemisphere · See more »

Stratocumulus cloud

A stratocumulus cloud belongs to a genus-type of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumulus, and the whole being at a lower altitude, usually below 2,400 meters (8,000 ft).

Stratus cloud

Stratus clouds are low-level clouds characterized by horizontal layering with a uniform base, as opposed to convective or cumuliform clouds that are formed by rising thermals.

Surface weather analysis

Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.

Temperature

Temperature is a physical quantity expressing hot and cold.

Thunderstorm

A thunderstorm, also known as an electrical storm, lightning storm, or thundershower, is a storm characterized by the presence of lightning and its acoustic effect on the Earth's atmosphere, known as thunder.

Weather map

A weather map displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings.

Weather Prediction Center

The Weather Prediction Center (WPC), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. government.
