Ask The Channel 3 Weather Team: What Is a Derecho?
Submitted By: Chris McKearneyQuestion:
What is a Derecho?
Answer:
A derecho is derived from the Spanish word meaning "straight".
The phenonemen is a widespread and long-lived, violent, straight-line windstorm that is associated with a fast-moving band of severe thunderstorms usually taking the form of a bow echo.
Derechos blow in the direction of movement of their associated storms, similar to a guest front, except that the wind is sustained and generally increases in strength behind the "gust" front.A warm weather phenomenon, derechos occur mostly in summer, especially July in the northern hemisphere. They can occur at any time of the year and occur as frequently at night as in the daylight hours.
Thanks to Dr. Walker Ashley , meteorology professor at Northern Illinois University snapped these pictures as a long-lived derecho with origins in North Dakota and southeast Saskatchewan.
Thanks for your question.
