How is the "feels like" temperature and wind chill calculated?

The feels‑like temperature on the city page is derived from a standard wind chill formulation that combines measured air temperature with wind speed at station height. When air temperatures are low and wind speed is higher, the perceived temperature can be several degrees colder than the actual value. In warm and humid conditions the same framework can be extended with a heat index, but the primary focus in Estonia is on wind‑related cooling.

Where do weather warnings for Viljandi come from?
