Temperature - The measurement of how hot or cold something is.

Thermometer - The instrument that measures temperature.

Thunder - The explosive sound of air expanding as it is heated by lightning.

Thunderstorm - A storm produced by a cumulonimbus cloud and always has lightning and thunder. Rain, hail and high winds may or may not occur.

Tide - The regular rise and fall of the Earth's oceans caused by the actions of the moon's and sun's gravitation acting on the rotating Earth.

Tidal Range - The difference in water level between high tide and low tide at a given place.

Tidal Wave - A destructive and high rise of water along a seashore. Tidal waves are caused by underwater earthquakes, volcanoes or landslides, and have nothing to do with tides.

Tornado - It begins as a funnel cloud with spinning columns of air that drop down from a severe thunderstorm. When they reach the ground they become tornadoes. Tornadoes are between 300 and 2,000 feet wide and travel at speeds of 20 to 45 miles per hour. They usually only last a few minutes, but their spinning winds, up to 300 miles per hour, can lift houses into the air and rip trees from the ground.

Tornado Warning - It’s issued to warn the public, emergency management, and other cooperating agencies when a tornado is forecast to occur or is occurring. The warning will include where the storm was occurring and where it’s expected to travel.

Tornado Watch - It’s issued when conditions are favorable for the development of tornadoes.

Tornado Alley - The portion of the United States where tornadoes occur most frequently. Tornado alley is between the Plains area from the Rocky Mountains on the west to the Appalachian Mountains on the east.

Trade Winds - Winds which blow from tropical high pressure belts toward the equatorial region of low pressure. In the Northern Hemisphere, the trade winds blow from the northeast.

Tropical Storm - It’s a low-pressure disturbance that forms over warm tropical ocean waters. In the United States, a tropical storm has winds between 39-73 m.p.h.

Tropical Depression - It’s a low-pressure disturbance that forms over warm tropical ocean waters and produces winds of 38 m.p.h. or less.

Trough - It’s an elongated area of low pressure.

Tsunami - A Japanese term for an unusually large ocean wave caused by undersea earthquake, landslide, or volcanic eruption. Only a few inches high in the open ocean, tsunamis steepen and rise in shallow water and can reach heights of 200 feet.

Typhoon - A hurricane in the western Pacific Ocean.
