Fog is created when a warm air mass moves over a colder area.http://www.komonews.com/weather/faq/4308457.html

Thunderstorms are generated by instability in the lower atmosphere. Usually warm moist air is forced to rise rapidly to form cumulonimbus clouds. http://www.tropicalweather.net/weather-thunderstorms.html

The exact processes that creates hail are still being studied. Traditionally, textbooks showed hailstones being formed as a water droplet was carried aloft with an updaft into subfreezing air and freezing. As the ice moved into a downdraft, more water coated the hailstone. http://www.tropicalweather.net/weather.html

Sleet is transparent frozen raindrops. Sleet or ice pellets are created when snow falls into air above freezing and melts into rain drops. http://www.tropicalweather.net/weather.html

Snow is the accumulation of crystal snowflakes. Snowflakes are made as water ice crystalizes. http://www.tropicalweather.net/weather.html

Tornadoes form in generally strong wind shear conditons. This is observed as winds increase in speed and change direction with increasing altitude.http://www.tropicalweather.net/weather-tornado.html

A pool of positively charged particles shadows the thunderstorm's movement. These positive charges will move up high objects like trees, buildings, and telephone poles.http://www.tropicalweather.net/weather-lightning.html

Rain is precipitation in liquid form. Precipitation occurs when water droplets in clouds become large enough to drop.http://www.tropicalweather.net/weather.html

Wind is the motion of air in the atmosphere. Wind is caused by an imbalance of heating from the sun. The uneven heating generates an unbalanced pressure field. http://www.tropicalweather.net/weather.html

Hurricanes form near the equator over warm ocean waters. http://scijinks.jpl.nasa.gov/hurricane/
