METEOROLOGY 0.0 / 5 ? AllhumidityUniversityNone Created by: Annal22Created on: 20-01-17 15:58 What is saturation vapour pressure? When water particles in the air are equal to those in the water. 1 of 16 An anemometer measures... wind speed. 2 of 16 Saturated vapour pressure is less over ice as.... Less water vapour can evaporate from ice, so there is less in the air above, and less is needed to balance it out. 3 of 16 Absolute humidity.... changes even when saturated vapour pressure doesn't. 4 of 16 What is the definition of dew point? The temperature at which air must be cooled in order to be fully saturated. 5 of 16 Hotter air can carry ........ water vapour, as evaporation is more likely/ more 6 of 16 A high dew point suggests that water vapour content is.... high 7 of 16 A wet bulb thermometer is useful as it cools by...... evaporative cooling 8 of 16 The temperature difference between a normal thermometer and a wet bulb thermometer is known as a ................... . depression 9 of 16 Relative humidity.... compares the amount of water vapour in the air with the amount required for full saturation. 10 of 16 At night, air cools by ....... conduction from contact with the ground. 11 of 16 Frost forms when air temperature is below freezing by a process known as ................ . deposition. 12 of 16 The substance on which water vapour can evaporate out is called...... cloud condensation nuclei. 13 of 16 According to the CLAW hypothesis, coccolithophores create sulphide gases which..... develop into aerosols, and act as CCN. 14 of 16 How is radiation fog formed? Water vapour condenses out when air at ground level cools upon contact with cool ground. 15 of 16 What is orographic lifting? Air is pushed up and over mountains, where it cools adiabatically. 16 of 16
