dust devil (alt. dust whirl, syn. remolino)

An intensely whirling column of air caused by a bubble of hot air caught between two cooler layers of air. Dust devils range from a foot to a mile high (30 cm. to 1.5 km.) mostly in arid regions; they spin dust and debris but can also shake houses and slam birds into trees.

Notes:

• This is version: 2.1     Last updated: February 4, 2002.

• If you are looking up names of plants, check the HortiPlex plant database here at GardenWeb.

• Proper nouns are generally not included in the glossary.

• Searches are case insensitive.

• You can browse the glossary, but there are many pages.

• Multiple keywords can be searched so that each word must appear in each hit (boolean "and") or so that only one of the words must appear (boolean "or").

• To increase the chances of matching keywords with multiple endings, search for "Word Roots." With this setting, epiphyt will match both epiphyte and epiphytic.

• You can also limit your search to just terms or just definition.

• Additional Passes: If there are no hits in the first search, common word endings (-ing, -es, -ed, -ly) are stripped from the keywords and a second pass is made. If there is still no match, all non-word characters are stripped.

• This glossary was compiled by the editors of GardenWeb from a variety of sources. It is updated continually.

• If you encounter any problems, or feel that there are terms that should be in the database and are not, please let us know.
