A white squall is a sudden and violent windstorm at sea which is not accompanied by the black clouds generally characteristic of a squall. The name refers to the white-capped waves and broken water, its meager warning to any unlucky seaman caught in its path. White squalls are rare at sea, but common on the Great Lakes of North America. A white squall is the culprit of many sea stories and blamed for quite a few tragedies. It is described as a sudden increase in wind velocity in tropical and sub-tropical waters, and lacks the usual dark, ominous squall clouds. The white squall (still thought by some to be myth) may be a microburst.〔''USA Today'': ("Answers: Oceans, waves, tides." ) Retrieved March 21, 2007.〕 ==Historical incidents== *The ''Pride of Baltimore'', a modern schooner, was reportedly struck by a white squall on May 14, 1986. The 121-ton vessel sank about north of Puerto Rico, casting the surviving crew members adrift for five days. The ''Toro'', a Norwegian freighter, picked them up at 2:30 a.m. May 19, 1986. An eyewitness account described it as follows:
″As described a white wall rose in front of our cruise vessel the Norwegian Gem as we were out in Boston in 2011, the ship listed 13 degrees to the port side as the wind started to blow out of no where and we could observe how the water rose upwards creating a white wall coming toward us.″ *A white squall was allegedly behind the sinking of the brigantine ''Albatross'' on May 2, 1961. *A white squall is also believed to have sunk the schooner ''Hunter Savidge'' on Lake Huron in 1899. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「white squall」の詳細全文を読む スポンサード リンク
