| thunderstorms | intense convectional storm characterized by thunder and lightning, short in duration and often accompanied by heavy rain, hail, and strong winds |
| tornado | intense low pressure system that generates wind speeds up to 300 mil/hour |
| trade winds | consistent surface winds blowing in low latitudes from the subtropical highs toward the inertropical convergence and southeast trades in the southern hemisphere |
| transpiration | transfer of moisture from living plants to the atmosphere by the emission of water vapor, primarily from leaf pores |
| Tropical easterlies | winds that blow from the east in tropical regions |
| Through | elongated area of low pressure |
| Unstable air | condition of parcel when it is warmer than surrounding atmosphere and is buoyant with a tendency to rise |
| Upwelling | upward movement of colder, nutrient-rich, subsurface ocean water, replacing surface water that is pushed away from the shore by winds |
| Violent weather | - unstable air+ cumulonimbus clouds+ hail+ squall lines |
| W.A.R. (wet adiabatic rate) | the air is rising and relative humidity is 100%; 3.3*/1000 |
| Westerlies | surface winds flowing from the polar portions of the subtropical highs, carrying fronts, storms and variable weather conditions from west to east through the middle latitudes |
| Wind | movement of air from one place to another because of differences in air pressure; air is going to flow from areas of high to low pressure |
| Windward | location on the side that faces toward the wind and is therefore exposed or unprotected; usually refers to mountain and island locations |
| Zones contention | areas that experience the effects of invading air masses |
