between 2970 K and 3090 K which contains 53% of a
all occurrences. The center of mass is !'it about
3010 K.

The mean daily snowfall curve is
relatively flat indicating that the equivalent
potential temperature explains very little of the
variation in the daily snowfal~. This is difficult
to reconcile since the adiabat~c condensate
increases with the equivalent ~potential tempera-
ture, all other effects being equal. It appears

An interesting bi-modal distribution is
seen in the snowfall curve with peaks at 2990 K
and 3110 K.
