Final answer:
Doppler radar is advantageous in weather forecasting as it can detect the movement of precipitation particles and provide accurate predictions. When a Doppler radar detects a mesocyclone signature, it takes forecasters a few minutes to identify its position and several hours to track its movement using radar data.
Step-by-step explanation:
The advantage of using Doppler radar in weather forecasting is that it can detect the movement of precipitation particles, such as raindrops or snowflakes, in addition to the intensity of the storm. This allows forecasters to track the movement of storms, identify potential areas of severe weather, and provide more accurate and timely predictions.
When a Doppler radar detects a mesocyclone signature, which is a rotating updraft in a thunderstorm, it typically takes forecasters a few minutes to identify its position. They then track its movement by analyzing radar data over time, which can take up to several hours. Finally, they use meteorological models and their expertise to forecast the future location and behaviour of the lonesomeness.
Therefore, the correct answer to the question is (b) minutes.
