Step 1: Understanding the Concept:
Meteorological parameters require specialized instruments for precise measurement in agricultural meteorology.
Measuring wind velocity (speed) is essential for predicting evaporation rates, managing pesticide spraying, and analyzing storm patterns.
Step 2: Detailed Explanation:
Let us define the function of each of the instruments listed:
An Anemometer is a device used for measuring wind speed and direction.
The most common type is the cup anemometer, which rotates at a speed proportional to the wind velocity.
A Barometer is used to measure atmospheric pressure, which is crucial for weather forecasting.
An Altimeter is used to measure altitude above a fixed level, typically sea level, and is widely used in aviation.
An Odometer is an instrument that measures the distance traveled by a vehicle.
Thus, wind velocity is measured by an anemometer.
Step 3: Final Answer:
Wind velocity is measured by an Anemometer.
