Rare Late-Season Lake Breezes in Southern Ontario
Come September or so in southern Ontario, daytime maximum
temperatures begin to rapidly decline while lake surface temperatures on
the Great Lakes remain relatively warm. Since the driving force of the
lake breeze is the difference in temperature between air over land and
air over lake, the frequency of these circulations also declines rapidly
in the fall months. However, conditions occasionally become conducive to
lake breeze development even into late fall. I have documented two recent
events of this nature. The first occurred on October 30, 1998 while the
second occurred on December 4, 1998. Click on the appropriate link below
for an account.
