A seasonal volume forecast, generally for a period centered around the time of spring snowmelt (e.g., April-July). The outlooks are in units of acre-feet and represent the expected volume of water to pass by a given point during a snowmelt season.

dry season"In certain types of climate, an annually recurring period of one or more months during which precipitation is at a minimum for that region; the opposite of rainy season.

Growing Season (Vegetation Season) Season during which meteorological conditions are favorable to the growth of plants. Gust Sudden brief increase of the wind speed over its mean value.

Growing season The number of days between the last spring freeze date and the first fall freeze date. to top of page H HaboobA dust or sandstorm that forms as cold downdrafts from a thunderstorm turbulently lift dust and sand into the air.

Growing Season- The period of time between the last killing frost of spring and the first killing frost of autumn. Gust- A brief sudden increase in wind speed. Generally the duration is less than 20 seconds and the fluctuation greater than 10 mph.

D1340 Dry season Period of the year characterized by the (almost) complete absence of rainfall. The term is mainly used for low latitude regions.

The Ozone Season During the warm season in North America, stronger sunlight and heat combine to convert industrial and transportation emissions into smog (ground-level ozone). This is particularly true for major metropolitan areas.

The seasonal shift of winds created by the great annual temperature variation that occurs over large land areas in contrast with associated ocean surfaces.

Autumn - The season of the year that is the transition period from summer to winter, occurring as the sun approaches the winter solstice.

SEASON A division of the year according to some regularly recurring phenomena, usually astronomical or climatic.

Climate Diagnostics Bulletin(CDB) - The monthly CPC Bulletin reports on the previous months' status of the ocean-atmosphere climate system and provides various seasonal ENSO-related outlooks. It is issued by the fifteenth of the month.

Pacific Decadal Oscillation(Abbrev. PDO) - a recently described pattern of climate variation similar to ENSO though on a timescale of decades and not seasons.

For example, it may be issued for the first snow of the season or when snow has not fallen in long while. Snow CoreA sample of either freshly fallen snow, or the combined old and new snow on the ground.

Wadi A valley, gully, or streambed in northern Africa and southwestern Asia that remains dry except during the rainy season. A stream that flows through such a channel. Wadi gauge Same as river gauge or stream gauge.

seasonal variation The change in a set of meteorological parameters averaged over three months. Seasonal variation is the largest climatic variation, and temperature is the most fre- quently observed meteorological parameter.

They are generally associated with fall and winter conditions, but can occur during any season. Nitrogen (N2) Weather: A colorless, tasteless, odorless gas that is the most abundant constituent of dry air. It comprises 78.09%.

The layers, troposphere, stratosphere, mesosphere, thermosphere, and the exosphere, vary around the globe and in response to seasonal changes. Troposphere stems from the Greek word tropos, which means turning or mixing.

climate The accumulation of daily and seasonal weather events over a long period of time. It is a description of aggregate weather conditions; the sum of all statistical weather information that helps describe a place or region.

If the winds reach 38 MPH, the system is called a tropical storm and given a name from a list for that season. For the Atlantic Ocean, the hurricane season is June 1 to November 30.

The Atlantic season lasts from June to November. The storm begins as a tropical depression, as anticlockwise circulation begins to develop around a rainy, deepening low-pressure area.

The ocean model forecasts seasonal changes in oceanic variables, such as sea surface temperature and ocean currents.

Monsoon -The word "monsoon" appears to have originated from the Arabic word mausim which means season.

MonsoonThe seasonal shift of winds created by the great annual temperature variation between land areas and ocean surfaces. The monsoon is associated primarily with stable winds which change their direction only 2 times in a year.

The Veteran's Day storm of November 9-14, 1996 may be the most severe early season lake effect snow (LES) storm the Great Lakes has witnessed in the past fifty years.

winter - Astronomically, between the winter solstice and vernal equinox in the Northern Hemisphere, and the summer solstice and autumnal equinox in the Southern Hemisphere; the coldest season of the year; ...

In the North Atlantic, the hurricane season is from May to November, but the majority of storms occur in August, September and October.

What is not clear, and has not been satisfactorily proven (or indeed disproved), is whether there is any season-by-season link between the ENSO variations (warm-normal-cold), and regional climates well away from the Pacific/Equatorial region, ...

a persistent wind throughout a season but often refers to the heavy rains that accompany them. Best known is the summer southwesterly monsoon over India followed by a northeasterly monsoon over Southeast Asia in winter.

MONSOON: A persistent seasonal wind, often responsible for seasonal precipitation regime. MOS: Model Output Statistics. MRF: Medium Range Forecast model generated every 12 hours by NCEP.

The term originally referred solely to the winds of the Arabian Sea which blow for about six months from the north-east (in winter) and for six months from the south-west (in summer), but now is also used for other marked seasonal winds.

CLIMATE: The historical record of average daily and seasonal weather events. CLOSED LOW: See Cutoff Low below. COASTAL FLOODING: The inundation of land areas along the coast caused by sea water above normal tidal actions.

Freeze Warning - Issued during the growing season when surface temperatures are expected to drop below freezing over a large area for an extended period of time, regardless if frost develops or not.

Mixing depth - the maximum height air pollution normally reaches. This varies with geography, season and time of day. Monsoon - A wind caused by differences in surface temperatures. Some produce heavy rains.

Antarctic Air: Mass of air originating in the Antarctic Continent. It is cold and dry in all seasons of the year.

Watch the weather forecast on television or read the weather map in the newspaper. Save the maps for a month or more. You can see changes over time and compare conditions over several weeks and seasons.

Specifically, it often refers to a southerly wind maximum in the boundary layer, common over the Plains states at night during the warm season (spring and summer).

Chaser Convergence - Any unplanned gathering of storm chasers, often near a storm of interest. These are seen regularly during the spring convective season.

Monsoon: a thermally driven wind arising from differential heating between a land mass and the adjacent ocean that reverses its direction seasonally.

Low-level Jet (abbrev. LLJ) - A region of relatively strong winds in the lower part of the atmosphere. Specifically, it often refers to a southerly wind maximum in the boundary layer, common over the Plains states at night during the warm season ...

rises during the day, relative humidity goes down because the moisture capacity of the air increases as temperature falls overnight, relative humidty goes up because the moisture capcity of the air decreases this pattern holds for all seasons ...

This boundary marks the top of the troposphere and the base of the stratosphere, and can vary with season and latitude, with a altitude ranging from 6 km (4 mi) in polar regions to 16 km (10 mi) in the tropics ...

The term refers collectively to the portions of the Earth where water is in solid form. It includes snow cover, floating ice, glaciers, ice caps, ice sheets, seasonally frozen ground and perennially frozen ground (permafrost).

If the forecaster feels that it is warranted, he or she can issued it for amounts less than the minimum criteria. For example, it may be issued for the first snow of the season or when snow has not fallen in long while.
