NEXRAD-NEXt Generation Weather RADar Overview

NEXRAD Radar is a Doppler radar system that has greatly improved the detection of meteorological events such as thunderstorms, tornadoes, and hurricanes. An extensive network of NEXRAD stations provides almost complete radar coverage of the continental United States, Alaska, and Hawaii.The range of each NEXRAD is 124 nautical miles. NEXRAD Abnormalities There are possible abnormalities regarding displayed NEXRAD images. Some, but not all, of those include:

Ground clutter
Strobes and spurious radar data
Sun strobes, when the radar antenna points directly at the sun
Military aircraft deploy metallic dust (chaff) which can cause alterations in radar scans
Interference from buildings or mountains, which may cause shadows

NEXRAD Limitations Certain limitations exist regarding the NEXRAD radar displays. Some, but not all, are listed for the user s awareness:

NEXRAD base reflectivity does not provide sufficient information to determine cloud layers or precipitation characteristics (hail vs. rain).
NEXRAD base reflectivity is sampled at the minimum antenna elevation angle. An individual NEXRAD site cannot depict high altitude storms at close ranges, and has no information about storms directly over the site.

Satellite Mosaic

Satellite Mosaic displays infrared composite images of cloud cover taken by geostationary weather satellites. The Satellite Mosaic provides up to seven levels of cloud cover.

Lightning

Lightning strikes are represented by lightning bolt icons, as shown in the images below. Lightning appears on the map if strikes were detected within the last seven minutes. The ground-based lightning detection network only detects cloud-to-ground lightning.

Storm Cells

The Storm Cells feature displays storms as well as the storm�s projected path in the immediate future.

Marine and Automotive units also show the size of the storm cell. The direction of the red cone indicates the projected path of the storm cell. The red bars that appear in the cone indicate where the storm will be in the future. Each bar represents 15 minutes.

Aviation units show the direction of the storm with an arrow. The tip of the arrow indicates where the storm should be in 15 minutes. Critical information about the storm cell can be viewed by selecting the storm cell with the map pointer.

Hurricanes

The Hurricanes feature shows the current position of a hurricane, tropical storm, or tropical depression, as well as its projected path (indicated by a red line). The darkened squares that appear along the red line display the projected locations received from the National Hurricane Center. The Center provides four forecasts at 12-hour intervals as well as a fifth forecast at a 24-hour interval.

Winds Aloft

Aviation units display winds aloft using wind barbs or a wind streamline depending on the zoom range of the map. Similar to Marine and Automotive units, the wind barbs indicate wind speed and direction. The wind streamline indicates wind direction with arrows.

Surface Pressure

This feature displays pressure isobars and pressure centers. The isobars connect points of equal pressure. Pressure readings can help determine weather and wind conditions in an area. High pressure areas are generally associated with fair weather. Low pressure areas are generally associated with clouds and the chance of precipitation. Isobars that are packed closely together show a strong pressure gradient. Strong pressure gradients are associated with areas of stronger winds. Pressure units can be displayed in Millibars (mb), Inches of Mercury (in), and Hectopascals (hPa).

Fronts

The Fronts feature displays lines indicating the leading edge of an air mass. This feature also displays pressure centers. Pressure centers are represented by a large Red "L" for low pressure centers or a large Blue "H" for high pressure centers. Pressure centers represent an area where pressure is measured to be either the highest or lowest relative to the surrounding area.

Visibility

Visibility is the forecast maximum horizontal distance that can be seen at the surface. Contour lines on the Visibility feature show the forecasted change in surface visibility. In the example below, visibility ranges from 1 mile to 4.5 miles.

METAR-Meteorological Aeronautical Reports

Meteorological Aeronautical Reports (METARs) are an international code used for reporting weather observations. If METAR data is available for an airport, a color coded flag is shown next to the airport.

AIRMET-AIRman's METeorological Information

An AIRMET (AIRman's METeorological Information) can potentially affect all aircraft. This data can be especially helpful for pilots of light aircraft that have limited flight capability or instrumentation. An AIRMET must affect or be forecast to affect an area of at least 3,000 square miles at any one time. AIRMETs are routinely issued for 6 hour periods and are amended as necessary due to changing weather conditions or issuance/cancellation of a SIGMET. AIRMETs are displayed as a colored dashed line.

AIRMET Sierra (IFR) (purple): Ceilings less than 1,000 feet and/or visibility less than 3 miles affecting over 50% of the area at one time. Extensive mountain obscuration.
AIRMET Tango (Turbulence) (orange): Moderate turbulence. Sustained surface winds of 30 knots or more at the surface.
AIRMET Zulu (Icing) (blue): Moderate icing. Freezing levels.

SIGMET-SIGnificant METeorlogical Forecast

A SIGMET (SIGnificant METeorlogical Forecast) advises of weather that is potentially hazardous to all aircraft. In the contiguous United States, items covered are: severe icing, severe or extreme turbulence, volcanic ash, dust storms, and sandstorms that lower visibility to less than three statute miles.

A Convective SIGMET is issued for: thunderstorms, isolated severe thunderstorms, embedded thunderstorms, hail at the surface, and tornadoes. A SIGMET is widespread. A SIGMET must affect or be forecast to affect an area of at least 3,000 square miles.

TFR-Temporary Flight Restrictions

Temporary Flight Restrictions or TFRs temporarily restrict all aircraft from entering the selected airspace unless a waiver has been issued. TFRs are routinely issued for occurrences such as sporting events, dignitary visits, military depots and forest fires. TFRs are represented as an area highlighted by Red (active) or Yellow (not yet active).

Echo Tops

Echo Tops are derived from NEXRAD radar and indicate the highest altitude at which precipitation is falling. Echo Tops at or above the altitude you select are displayed, in 5,000 foot increments up to 70,000 ft. Echo Tops can be helpful in determining the severity of thunderstorms. (higher = more intense)

Freezing Level Contours

Shows contours for the lowest forecast altitude where icing conditions are likely to occur.

Forecast

Forecast displays Fronts, High and Low Pressure Centers, and City Conditions. The forecast can be viewed in 12- hour increments for the next 48 hours.

TAF-Terminal Aerodrome Forecasts

Terminal Aerodrome Forecasts are issued by the National Weather Service for pilots. They include 24-hour forecasts on wind, visibility, expected weather conditions, and wind shear.

XM Radio

The XM Audio feature requires a subscription to XM Radio. Channels can be scanned by category and saved to a Favorites list. The XM audio output can be turned on and off.
