ULTRA VIOLET INDEX
The ultraviolet index or UV-Index (UVI) is an
international standard measurement of the
strength of sunburn-producing ultraviolet (UV)
radiation at a particular place and time. The
purpose of the UV Index is to help people
effectively protect themselves from UV
radiation. The UV Index is a linear scale, with
higher values representing a greater risk of
sunburn (which is correlated with other health
risks) due to UV exposure. An index of 0
corresponds to zero UV radiation, as is
essentially the case at night. An index of 10
corresponds roughly to midday summer sunlight
with a clear sky when the UV Index was
originally designed, but values above 10 are
sometimes possible. Levels above 8 are
considered “very high” and above 11 are
considered “extreme.”
WIND CHILL
Wind chill (popularly wind chill factor) is the
lowering of body temperature due to the
passing-flow of lower-temperature air. In other
words, the air “feels” colder than it is because of
the chilling effect of the wind on the skin.
