Base Velocity Radar

Distance from radar lat lon of selected location.

Base velocity radar. Nws oklahoma city ok topo radar counties rivers. However since the radar only measures radial velocity the strength of the wind will always be less than what is actually occurring unless the wind is moving directly toward or away from the radar. Product description base reflectivity is the most basic of all nexrad products and can be used to illustrate some fundamental principles. View other tool tx radar models including long range base composite storm motion 1 hour total and storm total.

National radar mosaic. Base velocity doppler radar for tool tx providing current static map of storm severity from precipitation levels. The velocity of the wind is measured in knots 1 knot 1 15 mph. The velocity is given in knots 10 knots 11 5 mph.

Reflectivity mean radial velocity and spectrum width as well as 40 products generated using computer algorithms. Precipitation moving perpendicular to the radar beam in a circle around the radar will have a radial velocity of zero and will be colored grey. Tropical storm isaias expected to make landfall in carolinas august 3 2020. The yellow dot in the center of the image is the radar s location.

Referred to as a base angle. This elevation gives the name base x to many radar products where x is one of many products such as reflectivity or velocity. When radar finishes scanning in 360 degrees at one elevation angle it tilts up to the next elevation angle and scans 360 degrees at that angle too. Tropical storm hanna to make landfall in texas july 24 2020.

Level ii and level iii nexrad data include three meteorological base data quantities. The base velocity image shows mainly green colors. For example a region with outbound wind in one radar will be represented by red colors. Distance from selected location.

Recall from base reflectivity the notch in the precipitation pattern at 2. With the option of viewing animated radar loops in dbz and vcp measurements for surrounding areas of tool and overall henderson county texas. Base velocity images provides a picture of the basic wind field from the elevation scan. Since these colors represent values relative to the radar to interpret these images correctly it is most important to know where the radar is located each velocity image.

The loop right above shows the comparison of the base velocity and storm relative motion. The atlantic is entering the most active weeks of hurricane season august 14 2020.
