High Wind Advisory- This product is issued when high wind speeds may pose a hazard. High Wind Warning- Issued when sustained winds will be 40 mph or greater for at least one hour, or any gust of wind expected to be 58 mph or greater.
High Wind Advisory This product is issued by the National Weather Service when high wind speeds may pose a hazard. The criteria for this advisory varies from state to state.
High Wind Advisory This product is issued by local National Weather Service Forecast Offices when high wind speeds may pose a hazard. The criteria for this advisory varies from state to state.
HIGH WIND: Sustained winds greater than or equal to 40 mph or gust greater than or equal to 58 mph. HUMIDITY: The amount of water vapor in the atmosphere. (See relative humidity).
High Wind- the sustained wind of forty mph or greater and/or gust greater than fifty-eight mph. Horse Latitudes- subtropical regions where anticyclones produce settled weather. Humidity- the amount of water vapor present in the air.
HIGH WINDS - Winds of 40 mph or greater lasting for an hour or more , and/or gusts to 58 mph or greater. HORIZONTAL VORTICITY- A rotation of air caused by vertical speed or directional wind shear.
High Wind Watch- Issued when conditions are favorable for the development of high winds over all of or part of the forecast area but the occurrence is still uncertain.
High Wind Warning: A high wind warning is defined as 1-minute average surface winds of 35 kt (40 mph or 64 km/hr) or greater lasting for 1 hour or longer, ...
HIGH WINDS DOWN BRANCHES; PP&L HANDLES POWER FAILURES The Morning Call Pennsylvania Power & Light Co.
High winds that occur a few hundred miles or so inland from the coast of a landfalling tropical cyclone. Tropical Cyclone Plan of the Day ...
Blizzard - High winds and reduced visibilities caused by blowing snow. Low temperatures as well. Exact definitions vary by region. Boundary layer - the part of the atmosphere closest to the ground.
High wind warningIssued when sustained winds from 40 to 73 mph are expected for at least one hour; or any wind gusts are expected to reach 58 miles per hour or more.
Channeled High WindsIn mountainous areas or in cities with tall buildings, air may be channeled through constricted passages producing high winds.
Strong cold fronts can set off atmospheric disturbances such as thunderstorms, squall lines, tornadoes, high winds and short duration snowstorms ahead of the moving cold front and cooler, drier weather as the front passes.
High winds raised dust-storms over adjacent inland pastoral stations - which were then isolated by floodwaters! ...
blizzard - A severe weather condition characterized by high winds and reduced visibilities due to falling or blowing snow. The U.S.
A vertical wind speed profile characterized by a relatively narrow current of high winds with slower moving air above and below. A large wind (speed) shear occurs above and below the jet axis.
Storm surge is the rising of the sea level due to the low pressure, high winds, and high waves associated with a hurricane as it makes landfall. The storm surge can cause significant flooding and cost people their lives if they're caught unexpected.
Alberta Clipper: A fast moving winter storm originating in the Alberta, Canada region. Often these snow storms have high winds reaching 100 km/h which reduce visibility through blowing and drifting snow.
For example, a warning or watch may be issued based on either a forecast or observation of severe thunderstorms, flash flooding, river flooding, high winds, winter storms, etc.
The tornado is fed by vertical instability of the atmosphere, covers a very small area, and has extremely high winds.
Because of its structure, the severe storm may last for hours beyond the lifetime of a normal thunderstorm while producing large hail, high winds, torrential rain, and possible tornadoes.
HAZARDOUS WEATHER OUTLOOK - A National Weather Service product outlooking expected weather related hazards for a given day. Such hazards may be convective, marine, and non-convective such as high winds or fog.
The Environment Canada has listed the following general criteria for issuing blizzard warnings in Canada: visibility less than 1 kilometer, wind speeds greater than 40 kilometers per hour, high windchill values ...
Because of the high wind speeds involved with jetstreams, any slight changes, in either velocity or direction, or both, leads to vertical motion in the air below the jet, and is a major player in the processes of atmospheric development.
