H

High risk (of severe thunderstorms): Severe weather is expected to affect more than 10 percent of the area.

High wind warning: Issued when sustained winds from 40 to 73 mph are expected for at least 1 hour; or any wind gusts are expected to reach 58 mph or more.

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. The criteria of a high wind watch are listed under the high wind warning and should include the area affected, the reason for the watch and the potential impact of the winds.

Hook echo: A radar pattern sometimes observed in the southwest quadrant of a tornadic thunderstorm. Appearing like a fishhook turned in toward the east, the hook echo is precipitation aloft around the periphery of a rotating column of air 2-10 miles in diameter.

Ice pellets: Precipitation of transparent or translucent pellets of ice, which are round or irregular, rarely conical, and which have a diameter of 0.2 inch (5mm), or less. There are two main types. Hard grains of ice consisting of frozen raindrops and pellets of snow encased in a thin layer of ice.

Ice storm: Liquid rain falling and freezing on contact with cold objects creating ice build-ups of 1/4th inch or more that can cause severe damage.

Ice storm warning: Older terminology replaced by winter storm warning for severe icing. Issued when 1/2 inch or more of accretion of freezing rain is expected. This may lead to dangerous walking or driving conditions and the pulling down of power lines and trees. A warning is used for winter weather conditions posing a threat to life and property.

Indian summer: An unseasonably warm period near the middle of autumn, usually following a substantial period of cool weather.

ISS: Integrated Sensor Suite. This is the part of the Davis Vantage Pro 2 that houses the rain collector, thermometer, hygrometer as well as the wireless transmitter. The anemometer also gets plugged into this device as well


J
Top

Jet streak: A local wind speed maximum within a jet stream.

Jet stream: Strong winds concentrated within a narrow band in the upper atmosphere. It normally refers to horizontal, high-altitude winds. The jet stream often "steers" surface features such as front and low pressure systems.


K
Top

Knot: A measure of speed. It is one nautical mile per hour (1.15 mph). A nautical mile is one minute of one degree of latitude.


L
Top

Lake effect: The effect of a lake (usually a large one) in modifying the weather near the shore and down wind. It is often refers to the enhanced rain or snow that falls downwind from the lake. This effect can also result in enhanced snowfall along the east coast of New England in winter.


M
Top

Macroburst: Large downburst with a 2.5 mile or greater outflow diameter and damaging winds lasting 5 to 20 minutes.

Mamma clouds: Also called mammatus, these clouds appear as hanging, rounded protuberances or pouches on the under-surface of a cloud. With thunderstorms, mammatus are seen on the underside of the anvil. These clouds do not produce tornadoes, funnels, hail, or any other type of severe weather, although they often accompany severe thunderstorms.

Maritime air mass: An air mass that forms over water. It is usually humid, and may be cold or warm.

Maximum temperature: The highest temperature during a specified time period.

Mean temperature: The average of a series of temperatures taken over a period of time, such as a day or a month.

Mercury barometer: An instrument that measures barometric pressure by measuring the level of mercury in a column.

Mesocyclone: A storm-scale region of rotation, typically around 2-6 miles in diameter and often found in the right rear flank of a supercell (or often on the eastern, or front, flank of an HP storm). The circulation of a mesocyclone covers an area much larger than the tornado that may develop within it.

Metar: A weather observation near ground level. It may include date and time, wind, visibility, weather and obstructions to vision, sky condition, temperature and dew point, sea level pressure, precipitation amount and other data used for aircraft operations.

Meteorologist: A person who studies meteorology. Some examples include research meteorologist, climatologist, operational meteorologist, TV meteorologist.

Meteorology: The study of the physics, chemistry, and dynamics of the atmosphere and the direct effects of the atmosphere upon the Earth's surface, the oceans, and life in general.

Microburst: A strong localized downdraft from a thunderstorm with peak gusts lasting 2 to 5 minutes.

Microclimate: A local climate that differs from the main climate around it.

MSL: Mean sea level. The average height of the sea surface, based upon hourly observation of the tide height on the open coast or in adjacent waters that have free access to the sea.


N

NWR: National Weather Radio.

NWS: National Weather Service.


P

Partly cloudy: Sky condition when between 3/10 and 7/10 of the sky is covered. Used more frequently at night.

Partly sunny: Similar to partly cloudy. Used to emphasize daytime sunshine.

Permafrost: A soil layer below the surface of tundra regions that remains frozen permanently.

Polar air: A mass of very cold, very dry air that forms in polar regions.

Polar front: The semi-permanent, semi-continuous front that encircles the northern hemisphere separating air masses of tropical and polar origin.

Polar stratospheric clouds (pscs): High altitude clouds that form in the stratosphere above Antarctica during the Southern Hemisphere winter. Their presence seems to initiate the ozone loss experienced during the ensuing Southern Hemisphere spring.

Polar vortex: A circumpolar wind circulation which isolates the Antarctic continent during the cold Southern Hemisphere winter, heightening ozone depletion.

Pressure: The force exerted by the interaction of the atmosphere and gravity. Also known as atmospheric pressure.

Pressure change: The net difference between pressure readings at the beginning and ending of a specified interval of time.

Pressure falling rapidly: A decrease in station pressure at a rate of 0.06 inch of mercury or more per hour which totals 0.02 inch or more.

Pressure gradient: The rate of decrease of pressure with distance at a fixed level.

Pressure gradient force: Force acting on air that causes it to move from areas of higher pressure to areas of lower pressure.

Pressure rising rapidly: An increase in station pressure at a rate of 0.06 inch of mercury or more per hour which totals 0.02 inch or more.

Pressure tendency: The character and amount of atmospheric pressure change during a specified period of time, usually the 3-hour period preceding an observation.

Pressure unsteady: A pressure that fluctuates by 0.03 inch of mercury or more from the mean pressure during the period of measurement.


R

RAID 1: RAID Redundant Array of Independent Disks. RAID 1 offers disk mirroring to help mitigate downtime from a physical drive failure.

Rain: Liquid water droplets that fall from the atmosphere, having diameters greater than drizzle (0.5 mm).

Rain foot: A horizontal bulging near the surface in a precipitation shaft, forming a foot-shaped prominence. It is a visual indication of a wet microburst.

Rain gauge: An instrument used to measure rainfall amounts.

Rain shadow: The region on the lee side of a mountain or mountain range where the precipitation is noticeably less than on the windward side.

Rain-free base: A horizontal, dark cumulonimbus base that has no visible precipitation beneath it. This structure usually marks the location of the thunderstorm updraft. Tornadoes most commonly develop (1) from wall clouds that are attached to the rain-free base, or (2) from the rain-free base itself. This is particularly true when the rain-free base is observed to the south or southwest of the precipitation shaft.

Rainbow: Optical phenomena when light is refracted and reflected by moisture in the air into concentric arcs of color. Raindrops act like prisms, breaking the light into the colors of a rainbow, with red on the outer, and blue on the inner edge.
