appearance as argument number 1

(documentation Squall EnglishLanguage "A Squall is a sudden, sharp increase in wind speed lasting minutes, as opposed to a wind gust, which lasts for only seconds. In 1962 the World Meteorological Organization (WMO) defined that to be classified as a squall, the wind must increase at least 8 metres per second (29 km/ h; 18 mph) and must attain a top speed of at least 11 metres per second (40 km/ h; 25 mph), lasting at least one minute in duration.[Wikipedia]")	Weather.kif 1813-1818
