derecho (dərā´chō), a long-lived windstorm over a wide expanse that is associated with a line of rapidly moving thunderstorms or showers. The winds in a derecho generally exceed 57 mph (92 kph) and may reach 100 mph (161 kph) or more; derecho winds are produced by clusters of downbursts, with stronger winds being produced by microbursts within downbursts. The line of storms associated with a derecho typically takes on a broadly curved or bowed shape, known as a bow echo from its appearance on radar. A serial derecho, usually associated with a strong, moving low pressure system, contains multiple bow echoes within a squall line that usually is hundreds of miles long and traverses an extensive area. A progressive derecho is typically associated with a weak surface low pressure area and with a line of thunderstorms less than 250 mi (400 km) long; the squall line usually remains relatively narrow as it progresses and may contain only a single bow echo. Hybrid derechos have characteristics of both serial and progressive derechos. Derechos typically cause so-called straight-line wind damage, in which the destruction is aligned in one general direction. Derecho winds can topple trees and power lines, overturn high-profile trucks and other vehicles, and even overturn mobile homes; the sudden, widespread destruction they cause can lead to prolonged power outages.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style
American Psychological Association
- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
