Early dew will minimize advantage. Dew factor will come into play. Will the bowlers overcome the challenge posed by dew?
You must have heard these lines while watching cricket matches. You guessed it right , we’re going to talk about the dew – but not about its role in cricket matches. Instead, let’s examine how dew is formed on the grass in the morning. Have you ever wondered where those glistening droplets clinging on to the blades of grass come from?
Water vapour is water in gaseous form. There is a lot of water vapour in the air. Warm air can hold more water vapour than cool air. At night, leaves, grass and stones cool more quickly than the air. Air passing over these cool objects gets cooled and then as it can no longer hold as much moisture as it could when it was warm, some of the water vapour leaves the air to form dew drops. Dew is this natural form of water that’s transformed through the process of condensation. Dew point is the temperature at which this happens.
Dew usually forms on surfaces that are not warmed by the heat coming off from the ground. This explains why we see the drops on stones, grass, leaves and even car roofs. As the evening turns colder, there is a chance that dew freezes to form frost.
Did you know that some species of plants depend on dew for their survival? Check out pine seedlings and lichens if you happen to visit a desert.
