GLOSSARY of TERMS for Kestrel Anemometers
|
WIND CHILL The chilling effect of the wind can be represented
by the lower temperature that would be required to produce the same
chilling sensation for a person walking in calm conditions. This
is known as the wind chill equivalent temperature and is an important
indicator in assessing the comfort of personnel spending periods
outdoors. It is not an indication that an unheated inanimate object
will cool below the ambient air temperature. Wet bulb temperature The temperature of the wet thermometer bulb in a wet and dry bulb hygrometer. The wet bulb is surrounded by wet fibres and evaporation of water from the fibres cools the wet bulb. The rate of evaporation depends on the relative humidity of the air. Density Altitude The altitude in the standard atmosphere corresponding to a specific air density. Dew Point The temperature at which dew or condensation begins to form. Relative Humidity The ratio, expressed as a percentage, of the actual vapour pressure to the saturation vapour pressure. |
