Fog, a
seemingly complex natural phenomenon, can be simply defined as the existence of
a cloud at or near ground level. For this reason, it is logical that fog
formation is more likely to occur in higher altitudes than in lower
elevations. A large portion of the development of fog can be attributed
to the accumulation of water vapor which condenses just above the earth's
surface. There are many common types of fog, such as radiation, valley,
advection, upslope evaporation, freezing, and forecasting. This picture,
taken on Saturday, February 10th, portrays a blanket of fog
that settled in the Blacksburg area, specifically over Lane Stadium.
Blacksburg is located in the Appalachian Mountain Range, and not surprisingly,
this area experiences plentiful amounts of fog all year long. While fog
may not seem as harmful as some other serious weather conditions such as snow
or ice, it can undoubtedly have a significant impact on everyday
activities. Fog, depending on its severity, can significantly reduce
vision capabilities and provide a serious obstacle that must be managed
carefully. Vehicles traveling in foggy areas are at an increased risk of
an accident, and serious fog can delay or even cancel commercial
flights. Afton Mountain, a stretch of highway on Interstate 64
near Charlottesville, was the sight of one of the most horrific traffic
collisions in Virginia over the last forty years. The lack of visibility
due to extreme fog created adverse traveling conditions causing a
fifty-four-vehicle crash which killed two people and injured forty others. Besides
the extreme life-threatening conditions initiated by fog, it often
provides many other less significant, but schedule altering experiences nonetheless. As
an avid golfer, I have often completed my early morning tournament
preparations, only to travel to a site to discover that my competition had
been cancelled or significantly delayed due to the lack of visibility created
by the impact of fog. Although seemingly benign, fog is
certainly a hazard that must be navigated using extreme caution in order
to prevent unnecessary damage which may be prevented if a little patience
is exercised.
