Assingment-1:: Difference Between Tropical and Temperate Cyclone

Tropical cyclones originate from thermal causes while temperate cyclones originate from dynamic causes related to the Coriolis effect and air mass movement. Tropical cyclones are typically smaller in size and affect a limited area, while temperate cyclones can cover a much larger region. Fog has significant impacts on transportation through delays and accidents. Dense fog reduces visibility to only tens of feet on highways, making driving dangerous. It costs billions annually in delays, accidents, and economic losses.

Effects of Fog:

The largest impacts of fog are to transportation, particularly airport operations and highway
travel, but also marine and rail travel. Impacts can range from annoyance due to delayed travel to
deadly multiple-vehicle highway accidents. Persistent, dense fog can ground or severely slow air
travel. Weather-related crashes, of which fog is one cause, cost an average of  $42
billion annually in the United States from personal injury, loss of life, and property damage. The
estimated cost of weather-related delay to trucking companies ranges from $2.2 to $3.5 billion
annually. Each year, $4.2 billion is lost due to air traffic delays attributed to weather.

Dense fog over highways can reduce visibility to only tens of feet making it dangerous to travel,
even with headlights.  The lower visibility and lack of contrast, especially at night, makes it
difficult for drivers to judge distance and speed. Our cues as to how fast we are traveling are
often taken from a reference to objects we see, such as trees, telephone poles, or signs. At night,
fog droplets scatter the light from headlights back to the eye reducing their effectiveness to
detect contrast. Road markings, signs and other objects may not be readily visible. Depth
perception may also be affected. Drivers may judge an object, like a car in front of them, to be
farther away that it is, thus delaying their reaction time. Dense fog has resulted in numerous
multi-vehicle pileups on roads in the United States and other countries. An added hazard during
the winter is freezing fog. Freezing fog occurs when the air temperature is below freezing and
the water droplets in the fog become supercooled.
