An anemometer is a device for measuring wind speed, and is a common weather station instrument. The term is derived from the Greek word anemos, meaning wind, and is used to describe any airspeed measurement instrument used in meteorology or aerodynamics. The first known description of an anemometer was given by Leon Battista Alberti around 1450.

Answer: (d)

There is a negative relationship between rainfall and pressure. When the air pressure is lower, more rainfall occurs. When there is low pressure in the atmosphere, the air bubbles that are rising, are always hotter than the air around.

If the ground is heated then air will rise. The cool air will produce condensation that will ultimately lead to rainfall.

Answer: (b)

An anticyclone is a region of high atmospheric pressure relative to the surrounding air, generally thousands of kilometres in diameter and also known as a high or high-pressure system.

Anticyclones appear on weather charts as a series of concentric, widely spaced isobars of 1000 mbs and above. The roughly circular closed isobar at its central region indicates the area of highest pressure.
