-|Available only from version 3.5.4: A variant on wind chill, calculated using the JAG/TI formula used in the UK, USA, Canada etc. The official formula of JAG/TI-2000 is:
+|Available only from version 3.5.4:[[Feels_Like|Feels Like]] page in weather terminology section of this Wiki explains.
-G(J) = 13,12+0,6215∗T−11,37∗(W∗3,6)0,16+0,3965∗T∗(W∗3,6)0,16(2.3) where air temperature, T, is in °C, is measured at 1.50 metres, and wind speed, W, is in m/s as measured at 10 metres.
-MX uses a slightly different formula, it is dependent on temperature, and can be expressed in PHP as:
-if($temp_degC < 10)
-{
-	$feels_like		= $wind_chill;
-}elseif($temp_degC > 20)
-{
-	$feels_like		= $apparent_temp;
-}else{
-	$app_temp_mult		= ($temp_degC - 10) / 10;
-	$wind_chill_mult 	= 1 - $app_temp_mult;
-	$feels_like		= ($apparent_temp * $app_temp_mult) + ($wind_chill * $wind_chill_mult);
