Channel 6 Radar Tulsa (2024)

FAQs

How can you tell how fast a storm is moving on radar? ›

Velocity data is derived from the phase, or doppler shift of the returned energy. The radar's computers will calculate the shift and determine whether the precipitation is moving toward or away from the radar, and how fast, then apply a corresponding color to those directions and speeds.

Like her tech tree cousins, Tulsa is capable of bringing all three turrets to bear while still keeping her belt angled enough to bounce most non-overmatching AP shells. Unlike the tech tree heavy cruisers, Tulsa's radar range is only 9km, the same as found on light cruiser IX Seattle.

The colors are typically a spectrum. The greens indicate light or moderate rainfall. Yellow, orange, and red indicate moderate to heavy rainfall and can also indicate hail. Whites or blues mean snowfall and pink indicates freezing rain, sleet, or a wintry mix.

Radar Beam Exercise

When navigating using VOR's, they used the 1-In-60 rule (i.e. if an aircraft is 60nm from a VOR and 1° off-track, the aircraft is 1nm off-track). But there is a more generic form of the rule that is useful for radar. Just take the radar range and add two zeros to find out what one degree equals.

Purple indicates “range folding”— where the radar cannot determine the radial velocity. Velocity image of a large-scale weather system. denotes the approx. location of the radar.

The WSR-88D is considered by many to be the most powerful radar in the world, transmitting at 750,000 watts (an average light bulb is only 75 watts)! This power enables a beam of energy generated by the radar to travel long distances, and detect many kinds of weather phenomena.

Transmitted Power

For example, 1dB more of output power in a Long Range Radar (LRR) will give us 2.8m to detect a bike, 6m for a motorbike and 11m for a typical car, as shown in Figure 4.

On a weather radar map, a tornado is usually indicated by a smaller area of red surrounded by a larger area of green. However, modern radar systems can also indicate debris balls, a sign of a tornado on the ground.

So, if you see a radar map using this scale, black would indicate “no echo” which basically means the radar did not get any measurement for the black areas of the map. Purple, on the other hand indicates intense echos were received by the radar and most likely very intense rain with large hail possible.

What does purple mean on a weather channel radar map? ›

Purple= Extremely heavy rain or hail.

The basic technique for calculating the storm-relative velocity is to determine the component of the average storm motion toward/away from the radar for each azimuth and subtract that value from the measured radial velocity for each pixel along the azimuth.

Yes, moving radar can clock other vehicles speeds while the officer's vehicle is moving both going in the same direction or even in opposing directions. These radar guns have a second antenna that measures the patrol cars speed while the other antenna tracks the target vehicle.

When you see red wrapped in green like in the video above that is called a TVS, a Tornado Vortex Signature. A TVS is a very tightly concentrated area of rotation (high above the ground, several kilometers) hence you have a small area with green and red wrapped together (movement towards and away from the radar).
