Those who live in northern portions of the United States expect cold weather during the winter months.
Maritime Continent is the name given primarily by meteorologists to the region of Southeast Asia which comprises many islands, peninsulas and shallow seas.
continentality"In climatology, the degree to which a point on the earth's surface is in all respects subject to the influence of a landmass; the opposite of oceanicity (or oceanity).
CONTINENTAL AIR MASS: A dry air mass originating over a large land area.
Continental climate - a drier climate with great temperature extremes throughout the year.
Convection - Air moving up and down in a quasi-circular flow, called a cell.

Continental Climate A climate lacking marine influence and characterized by more extreme temperatures than in marine climates: therefore, it has a relatively high annual temperature range for its latitude.
Continental drift The slow movement of continents which are parts of gigantic plates, across the face of the globe.
Continental arctic air mass An air mass characterized by extremely low temperatures and very dry air.
Continental polar air mass An air mass characterized by low temperatures and dry air. Not as cold as arctic air masses.

Continental Shelf (CONSHELF) The zone bordering a continent and extending to a depth, usually around 100 fathoms (600 feet), from which there is a steep descent toward greater depth.
Continent One of the large, continuous areas of the Earth into which the land surface is divided.
Continental (air mass)-A dry air mass that forms over land.
Continental climate-The climate of the centers of continents, with cold winters and warm or hot summers.
Continental Polar air forms over the high latitudes of North America, Europe and Asia. This air mass has low surface temperatures, is very stable, with low moisture.

Convection - Transfer of heat by fluid motion between two areas with different temperatures. In meteorology, the rising and descending air motion caused by heat.
With a smaller continental area separated from polar regions by the Southern Ocean, Australia escapes the harsh outbreaks of true polar air which invade northern hemisphere continents during winter.

CONTINENT A large land mass rising abruptly from the deep ocean floor, including marginal regions that are shallowly submerged. Continents constitute about one-third of the earth's surface.
continental crust The layer of the Earth that lies under continents and the continental shelves. It ranges in thickness from 35 to 60 km. Its upper layer has a density of 2.7 g/cm3 and is composed of rocks that are rich in silica and alumina.
a pressure pattern which allows stagnation of the air - and this usually means a slow-moving anticyclone such as is found in the great sub-tropical high pressure belts, the polar high pressure regions or the Asiatic (or other great continental) ...
Global Temperature ChangeThe net result of four primary factors including the greenhouse effect, changes in incoming solar radiation, altered patterns of ocean circulations, and changes in continental position, topography and/or vegetation.

A summer high over the North American continent brings moist, unstable maritime tropical air from the Gulf over the Mississippi Valley. The thunderstorms that result are the principal source of moisture for this region.
The system uses satellite transmitting (i.e. "uplink") equipment at more than 58 major NWS forecast offices throughout the continental U.S., Alaska, Hawaii and Puerto Rico.
For characterizing the moisture distribution, air masses are distinguished as to continental (c) and maritime (m) source regions.
There are two main types of glacier: mountain glaciers which form at altitude among mountain peaks and valleys; and continental glaciers, which form over continents at high latitude.
Model Output Statistics - the Hydrometeorological Center (HPC) produces a short range (6 to 60 hours) MOS guidance package generated from the NGM, GFS, and ETA models for over 300 individual stations in the continental United States.
The doctor is also used in the African tropics to describe a sea breeze which generally brings cool relief from the heat generated in the interior of the continent.
It forms as continental air cools below the temperature of a nearby maritime airmass and sets up a thermally driven circulation. The land breeze is occasionally refered to as a katabatic wind. See also Sea breeze.
A body of air that extends hundreds or thousands of kilometers horizontally and is relatively uniform in temperature and moisture content (see continental arctic, continental polar, continental tropical, maritime polar, ...
Continental polar air (cP) is formed over cold surface regions and is typically very stable with low moisture. Maritime polar air (mP), produced over warmer waters, is less stable with high moisture.
Long period waves of low height that travel along the continental shelf and may modify coastal water levels off New South Wales by up to 0.2m. Shelf waves are generated e.g.
Antarctic Front: Front that develops and persists around the Antarctic Continent, approximately between latitudes 60º and 65ºS, and separates the Antarctic Air Mass from the Maritime Polar Air Mass (Pm) further to the north.
Droughts can affect a fairly small area for a season or an entire continent for years. Too little rainfall can cause shortages in the water supply, destroy crops, and cause widespread hunger.
Convective outlook (sometimes called the AC) - A forecast containing the area(s) of expected thunderstorm occurrence and expected severity over the Continental US, issued several times daily by SELS.
