downdraft
[หdaสnหdrรฆft ]
Definition
meteorology
A downdraft is a downward-moving air current typically associated with thunderstorms and other severe weather phenomena. It occurs when cool air sinks rapidly towards the ground, often resulting in gusty winds and changes in pressure. Downdrafts can lead to various weather effects, including increased precipitation and the potential for severe weather conditions like hail or tornadoes. They are a critical component of storm dynamics and can significantly influence local weather patterns.
Synonyms
Examples of usage
- The downdraft from the storm caused a sudden drop in temperature.
- Pilots must be cautious of downdrafts when flying near thunderstorms.
- The intense downdraft created strong gusts of wind in the valley.
- Farmers were alerted to the downdraft conditions that could damage crops.

Interesting Facts
Meteorology
- Downdrafts can occur during thunderstorms, causing rapidly falling air that can lead to heavy rainfall.
- They are responsible for creating gusty winds that can suddenly change direction and intensity.
Aerodynamics
- In aviation, downdrafts can pose a hazard to small aircraft, especially during landing and takeoff.
- Pilots need to be aware of downdrafts, as they can cause unexpected altitude changes.
Environmental Science
- These air currents can help disperse pollutants by mixing them with the lower atmosphere.
- Studying downdrafts helps scientists understand weather patterns and improve forecasting techniques.
Cultural References
- In literature, downdrafts can symbolize disturbance and chaos, often representing a sudden change in a characterโs fortune.
- Movies depicting storms often show downdrafts as a dramatic element, emphasizing the power of nature.
Origin of 'downdraft'
The term 'downdraft' originated in the English language in the mid-20th century, combining the prefix 'down-', indicating movement towards a lower position, with the noun 'draft', which refers to the flow of air. This term emerged from the study of meteorological phenomena, particularly in relation to severe weather patterns like thunderstorms. The understanding of downdrafts became crucial for meteorologists and pilots, as these downdrafts can greatly affect air travel and weather forecasting. As weather technology and research have advanced, so has the significance of understanding downdrafts in predicting severe weather events. The concept also found usage in aviation to describe the effects of downdrafts on aircraft performance, leading to enhanced safety protocols.
