LONGITUDE The location east or west in reference to the Prime Meridian, which is designated as zero (0) degrees longitude.
longitude"The angular distance along the equator measured from the prime meridian to the meridian of the point in question. Compare latitude.

longitude: the distance in degrees on the earth measured East and West from the Prime Meridian (in Greenwich England).
Longitude The angular distance measured east or west of a prime meridian from a point at the center of the Earth. A line connecting all points of the same longitude is called a meridian.
Longwave Radiation See infrared radiation.
Longitude The angular distance from the Greenwich meridian (0°), along the equator. This can be measured either east or west to the 180th meridian (180°) or 0° to 360° W.
Active Longitude
In solar-terrestrial terms, the approximate center of a range of heliographic longitudes in which Active Regions are more numerous and more flare-active than the average.
Active Prominence ...
Longitude - The position of the Earth's surface east or west of the Greenwich meridian.
Central Meridian Passage (CMP)In solar-terrestrial terms, the passage of an Active Region or other feature across the longitude meridian that passes through the apparent center of the solar disk.CENTROIDThe center of mass of a storm.
TELECONNECTIONS Information used by forecasters to determine what the weather might be elsewhere when compared with past weather conditions at the same degree of longitude.
Offshore WatersThat portion of the oceans, gulfs, and seas beyond the coastal waters extending to a specified distance from the coastline, to a specified depth contour, or covering an area defined by specific latitude and longitude points.
Airport Location: An aiport location shown as the latitude and longitude.
Air Pressure: Air pressure is equal on all sides.
Air Pressure: Air pressure is the same in and out of doors.
Air Pressure: Is measured with a "Barometer".
On many occasions, particularly in mid-latitude/temperate zone regions, the flow is directed more or less directly from west to east, crossing few latitude zones within the same longitude range: this is a 'highly zonal' type - any short-wave ...
Location of the drop, indicated by the latitude, longitude, and Marsden Square.
It includes the location of the storm center in latitude and longitude and in distance from a well known point. The current movement is given to 16 points of the compass.
Weather data is reported in Coordinated Universal Time (UTC) and this system is based upon a 24-hour clock of time measured along the Prime Meridian (0 degrees longitude) in Greenwich, England.
The best track contains the cyclone's latitude, longitude, maximum sustained surface winds, and minimum sea-level pressure at 6-hourly intervals.
This is also the Prime Meridian of Longitude. The globe is divided into twenty-four (24) time zones of 15 degrees of arc, or one hour in time apart.
Centred on zero degrees longitude. For scientific purposes this time zone is also known as Universal Time (UTC). All meteorological observations worldwide are reported using this time (for ease of comparison and computation).
The coded points are identified by degrees and tenths of latitude and longitude and are in a clockwise direction around each isohyet. For points west
of 99.9 degrees west longitude, the leading 1 is omitted from the coding.

Each 10 degree latitude by 10 degree longitude grid was to have at least two meteorological stations, for a total of about 2600 stations worldwide.
Meridional Flow: Large-scale atmospheric flow in which the north-south component, i.e., flow parallel to the longitude lines or meridians, is much greater than the zonal east-west)component. Compare with zonal flow.
meridional - In meteorology, a flow, average, or functional variation taken in a direction that is parallel to a line of longitude; along a meridian; northerly or southerly; as opposed to zonal.
GPS: Global Positioning System, a navigation system which uses a constellation of artificial earth satellites to make precise determinations of the latitude and longitude of locations on the earth's surface or in the atmosphere.
