It refers to a mode of Doppler radar. You're probably used to looking at base reflectivity, which measures the intensity of precipitation within range of the radar. Base velocity measures the velocity at which any object, even wind, is moving toward or away from the radar. This is especially useful in identifying rotation (potential tornadoes), but also to diagnose other features such as cold air advection.

Where does the weather comes from?
the weather comes from the sky
Weather report says winds blow at 5km h from northeast is this description of the wind speed or velocity?
Velocity is the report on the weather. This is what measures speed and direction.
Calculate distance from a velocity time graph?
The area between the graph and the x-axis is the distance moved. If the velocity is constant the v vs t graph is a straight horizontal line. The shape of the area under the graph is a rectangle. For constant velocity, distance = V * time. Time is the x-axis and velocity is the y-axis. If the object is accelerating, the velocity is increasing at a constant rate. The graph is a line whose slope equals the acceleration. The shape of the graph is a triangle. The area under the graph is ½ * base * height. The base is time, and the height is the velocity. If the initial velocity is 0, the average velocity is final velocity ÷ 2. Distance = average velocity * time. Distance = (final velocity ÷ 2) * time, time is on the x-axis, and velocity is on the y-axis. (final velocity ÷ 2) * time = ½ time * final velocity ...½ base * height = ½ time * final velocity Area under graph = distance moved Most velocity graphs are horizontal lines or sloping lines.
What is the coldest weather in mawson base?
The coldest weather in mawson that has been recored is -34.c
How does iron weather?
it comes a elephant and then turns into a lion
What is a special type of weather radar that can be used to track severe weather by detecting wind speed and direction?
Doppler radial velocity, rather than the usual base reflectivity scans.
What do you mean by weather change?
atmospheric pressure increases atmospheric pressure decreases wind velocity increases wind velocity decreases rain begins to fall rain stops snowfall or other precipitation begins precipitation ends cold front comes in warm front comes in
Where does weather comes from?

Weather report says winds blow at 5km h from northeast is this description of the wind speed or velocity?
Velocity is the report on the weather. This is what measures speed and direction.
What does red on weather radar mean?
Depending on the product, it can mean either very heavy rain or pea size hail, or winds moving torwards the radar site if you are looking at Storm relative mean velocity or base mean velocity products.
How does an anemometer measure the weather element?
wind velocity
Which of these is an sl base unit minute second velocity?
Second minute: the si base unit for time is secondvelocity: the si base unit for velocity is meters / second (m/s)
How are clouds and weather related?
weather comes from clouds
What kind of weather comes in the winter?
Cold weather.
Wind velocity may be roughly indicated by?
spacing of isobars on a weather map
As wind velocity decreases the distance between isobars on a weather map will?
Increase. Isobars represent lines of constant atmospheric pressure, and when wind velocity decreases, the pressure gradient weakens. A weaker pressure gradient results in isobars being spaced further apart on a weather map.
