Free CBM Radar & Satellite Meteorology Questions and Answers

Question 1

What is the primary function of weather radar?

Accepted Answer

Detect precipitation

Answer

The primary function of weather radar is to detect precipitation. It works by emitting microwave pulses that reflect off precipitation particles like rain, snow, or hail. By analyzing these reflected signals, radar can determine the location, intensity, and movement of precipitation, providing critical information for short-term forecasts and severe weather warnings.

Question 2

Which radar product shows the relative motion of precipitation toward or away from the radar?

Accepted Answer

Velocity

Answer

Velocity radar products utilize the Doppler effect to measure the speed and direction of precipitation particles relative to the radar. This allows meteorologists to identify areas of wind shear, rotation within storms (which can indicate tornado formation), and the overall movement of storm cells. It provides crucial insights into storm dynamics.

Question 3

What does an infrared satellite image primarily depict?

Accepted Answer

Cloud temperature

Answer

An infrared satellite image primarily depicts cloud temperature by detecting the thermal radiation emitted by clouds and the Earth's surface. Colder temperatures, typically associated with higher clouds, appear brighter, while warmer temperatures, indicating lower clouds or clear ground, appear darker. This allows meteorologists to determine cloud height and type, even during nighttime.

Question 4

Which type of satellite orbit provides continuous coverage of the same area?

Accepted Answer

Geostationary orbit

Answer

A geostationary orbit provides continuous coverage of the same area on Earth. Satellites in this orbit match Earth's rotation period, appearing stationary relative to a fixed point on the ground. This allows for constant, real-time monitoring of a large geographic region, which is invaluable for tracking rapidly developing weather events.

Question 5

Dual-polarization radar helps improve detection of which weather phenomenon?

Accepted Answer

Precipitation type

Answer

Dual-polarization radar significantly improves the detection and identification of precipitation type. By transmitting and receiving both horizontal and vertical radar pulses, it gathers more detailed information about the shape and size of precipitation particles. This allows meteorologists to better distinguish between rain, snow, hail, and even non-meteorological targets like debris, enhancing forecast accuracy.
