Does the outside temperature go lower if you are ...

Hi,
1.  The outside temperature is not effected by the speed
     of the plane.
2.  The higher your plane goes the lower the teperature is.
3.  Same applies when you drive. 
4.  The wind cools you when you are exposed to it
     (that's the reason a vetilator makes you feel more 
     comfortable when it's getting warm.... It doesn't
     decrease the temperature outside but does cools
     you (the amount depends on several factors: 
     The temp., your body's temp, wind velosity, etc.).
Best regards,
