    The variation in atmospheric pressure reading gives an early indication of the weather that may be encountered depending upon the fact that whether the pressure is rising or falling. For eg rapidly falling pressure reading may indicate formation of low pressure area nearby the vessel and that tough weather is likely to be experienced. Hence, atmospheric pressure readings are quite useful in predicting the weather pattern vessel may encounter.

    Whirling psychrometer consists of a set of ’dry’ and ’wet’ bulb thermometers. It is used to calculate the Relative Humidity of the atmosphere. In order to get the accurate readings of the dry and wet bulb thermometers, the whirling psychrometer is rotated. This is because the maximum depression of the wet bulb will depend upon the rate of evaporation.And, it is determined that the maximum rate of evaporation will happen when the speed of wind flowing through it is greater than 7 knots. This can be achieved by rotating the whirling psychrometer. Rotation of psychrometer will result in generation of (more)
