Light Wind

Breeze - A light wind.
Ceiling - The height of the lowest layer of broken or overcast cloud layer.

 


The area of light winds within 10 degrees of the equator.
Doppler Radar
Sophisticated radar that can measure the speed and direction of moving objects, such as wind.

DOLDRUMS - Very light winds that persist over the equilateral regions of the earth. The normally blow from an Easterly direction.

Thermal BeltA zone of high nighttime temperatures (and relatively low humidities) that is often experienced within a narrow altitude range on valley sidewalls, especially evident during clear weather with light winds.

During this time, the light winds cannot "cleanse" the buildup of smoke, dust, gases, and other industrial air pollution.

The Horse Latitudes is the name of the belt of calms, light winds and fine, clear weather between the trade wind belts and the prevailing westerly winds of higher latitudes.

Hurricanes originate over the tropical and subtropical North Atlantic and North Pacific oceans, where there is high humidity and light wind. These conditions prevail mostly in the summer and early fall.

The examples of vertical wind profiles are similar to those that have been observed with different storm types: from the chaotic, light winds of unorganized summer storms, to the veering and increasing winds typical of organized storms.

87 inches in the Lehigh Valley and brought heavy fog but only light winds and no reports of flooding, according to the National Weather Service. The fog moved in about 4 p.m.

hurricanes: tropical storms with winds exceeding 74 mph originating over the North Atlantic and North Pacific oceans near high humidity and light winds.

eye - In meteorology, usually the "eye of the storm" (hurricane, typhoon), that is, the roughly circular area of comparatively light winds found at the center of a severe tropical cyclone and surrounded by the eyewall.

Highs are frequently associated with light winds and subsidence. Subsidence will generally evaporate most cloud droplets after less than 500 meters, due to adiabatic heating. Thus, high pressure typically brings clear skies.

Ridge used by itself refers to an area of high pressure, characterized by low dewpoints, sunny skies, and light winds. However, when combined with the word hostile it has a somewhat different meaning.

EYE The center of a tropical storm or hurricane, characterized by a roughly circular area of light winds and rain-free skies. An eye will usually develop when the maximum sustained wind speeds exceed 78 mph.

Doldrums: The equatorial belt of calms or light winds, variable in direction, between the two systems of trade winds.
Drizzle: Minute droplets of water (less than 0.5 mm [1/50 inch] in diameter), uniformly disperse, which precipitate on the earth.

Atmospheric stagnation A condition of light winds and poor vertical mixing that can lead to a high concentration of pollutants.

This index was devised for shady, light wind conditions. Exposure to full sunshine can increase Heat Index (HI) values by up to 15°F. Also strong winds, particularly with very hot, dry air, can be extremely dangerous.

Eye - A roughly circular area of relatively light winds and fair weather at the center of a hurricane.
Eye Wall - The doughnut-shaped area ofintensive cumulonimbus development and very strong winds that surrounds the eye of a hurricane.

Eye: The roughly circular area of comparatively light winds that encompasses the center of a severe tropical cyclone. The eye is either completely or partially surrounded by the eyewall cloud.

Eye - the roughly circular area of a tropical cyclone marked by only light winds or completely calm with no precipitation
Eye Wall- the collection of thunderstorms which generally surround the eye of a hurricane ...

Indian Summer: A period in mid to late Autumn in the eastern United States and eastern Canada characterized by light winds, clear skies and temperatures which are unseasonably warm during the day and refreshingly chill at night.

eye—The roughly circular area of calm or relatively light winds and comparatively fair weather at the center of a well-developed tropical cyclone. A wall cloud marks the outer boundary of the eye.
F ...

The centre of a tropical cyclone, characterised by a circular area of light winds and rain free skies. They can range in size from about 10km to 90km.
Eye wall ...

The five most important factors for forecasting fog formation are 1) long nights during colder months; 2) clear skies and light winds; 3) moist air; 4) a low-level temperature inversion and the 5) sufficient supply of condensation ...

An inactive or 'break' period occurs when the monsoon trough temporarily weakens or retreats north of Australia; it is characterised by light winds, isolated shower and thunderstorm activity, sometimes with gusty squall lines
(see Fig. 1(b)).

This usually occurs when the same air mass is parked over the same area for several days. During this time, the light winds cannot "cleanse" the buildup of smoke, dust, gases, and other industrial air pollution.

by exhaust particles from the vessel acting as condensation nuclei, and 'seeding' the humid, near sea surface environment, and betraying the presence of the ship by a thin band of water droplets which are not dispersed due to the very light winds and ...
