A weather map provides a view of weather elements over a specified geographical area at a specified time and was invented by Sir Francis Galton.
Look at the weather map on the left.
It shows the weather for Thursday (15/6/00).
Predict which day of the following weekend would be the best day to have a picnic in Melbourne, Saturday(17/6/00) or Sunday(18/6/00)?

Weather Map: A graphical model which integrates weather observations.
Weather Modification: To change of alter the weather.
Weather maps that are produced for the portion of the atmosphere above the lower troposphere, generally at and above 850 mb. Isolines on these maps usually represent the heights of a constant pressure surface, such as the 500 mb surface.

Use a weather map to look up the temperatures of cities around the world and discover how hot each gets in the summer and how cold each gets in the winter. Compare these figures with your town.
On the weather map an area between two highs and two lows.
Cold Front
The leading edge of a colder mass of air that displaces a warmer mass of air.
Line on a weather map joining points of equal pressure.
Isotherms
Lines drawn through positions with the same temperatures.
A line on a weather map linking areas with equal air pressure

A line drawn on a weather map connecting points of equal pressure is called an "isobar". Isobars are generated from mean sea-level pressure reports and are given in millibars.
Isobar- A line on a weather map that surrounds an area with the same atmospheric pressure.
Isotherm- A line on a weather map that surrounds an area with the same temperature.
The line drawn on a weather map connecting points of equal barometric pressure.
ISODROSOTHERM
The line drawn on a weather map connecting points of equal dew point.

Station ModelA specified pattern for plotting, on a weather map, the meteorological symbols that represent the state of the weather at a particular observing station.Station PressureThe absolute air pressure at a given reporting station.
Cold PoolA region of relatively cold air, represented on a weather map analysis as a relative minimum in temperature surrounded by closed isotherms.
meteorological symbol"A letter, number, diagrammatic sign, or character used in weather records or on weather maps to indicate meteorological phenomena, both past and present, in a concise and accurate form.
The isobars on a weather map are usually drawn with a 4 mb contour interval, so to get the pressure gradient we multiply the above figure by 4 divided by the distance between the isobars in degrees of latitude.
upper-air weather chartWeather maps that are produced for the portion of the atmosphere above the lower troposphere, generally at and above 850 millibars.
Isopleth A line on a weather map connecting constant thickness (layer of atmosphere).
Isotach A line on a weather map connecting points of equal wind speed.
Isotherm A line on a weather map connecting points of equal temperature.
ISODROSOTHERM The line drawn on a weather map connecting points of equal dew point.
ISOHEL A line drawn through geographic points having equal duration of sunshine or another form of solar radiation during a specified time period.
ISOBAR: A line of equal barometric pressure on a weather map.
ITCZ: Inter-tropical Convergence Zone.
Isobar - A line on a weather map that connects points of equal pressure. On a weather map, isobars extend around areas of high and low pressure.
Isobars Lines drawn on a weather map joining places of equal barometric pressure.
Isothermal Of or indicating equality of temperature.
Isotherms Lines connecting points of equal temperature on a weather map.
Isobar- the line of equal pressure denoted on surface weather maps.
Isotherm- the line of equal temperature denoted on surface weather maps.

Air pressure tendency Change in air pressure with time; on a surface weather map, the air pressure change over the prior 3 hours.
Albedo The fraction or percent of radiation striking a surface that is reflected by that surface.
Most high and low pressure areas seen on weather maps are synoptic-scale systems.

Synoptic scale The typical weather map scale that shows features such as high- and low-pressure areas and fronts over a distance spanning a continent. Also called the cyclonic scale.

synoptic chart—A chart, such as the familiar weather map, which depicts the distribution of meteorological conditions over an area at a given time.
T
target—In radar, any of the many types of objects detected by radar.
The saddle point (sometimes called a "col") refers to a point in the air pressure pattern depicted on a weather map.
'the air temperature' and it is these values that appear, for example, in the World Cities reports in newspapers/teletext, or plotted on standard synoptic charts, and also it is at this level that the forecast temperatures seen on tv weather maps are ...
Geostrophic wind - a theoretical wind which blows along the isobars on a weather map. Pretty good of actual winds high above the ground.
col - (Also called saddle point, neutral point.) In meteorology, the point of intersection of a trough and a ridge in the pressure pattern of a weather map.
ISOBAR - A line connecting equal points of barometric pressure, which are usually depicted on weather maps and charts by meteorologists.

INVERTED TROUGH - A trough of low pressure appearing as an "upside down" trough on a weather map. These are troughs where the flow they are embedded in is from an Easterly direction in the Northern hemisphere.
Synoptic Scale (or Large Scale) - Size scale referring generally to weather systems with horizontal dimensions of several hundred miles or more. Most high and low pressure areas seen on weather maps are synoptic-scale systems.
Station model: An efficient method of representing weather conditions at a single location graphically on a weather map.
WaveIn meteorology any pattern identifiable on a weather map that has a cyclic pattern or a small cyclonic circulation in the early stages of development that moves along a cold front.
