Chinooks become less frequent further south in the United States, and are not as common north of Red Deer, but they can and do occur annually as far north as High Level in northwestern Alberta and Fort St. John in northeastern British Columbia, and as far south as Albuquerque, New Mexico. In southwestern Alberta, Chinook winds can gust in excess of hurricane force [120 km/h (75 mph)]. On November 19, 1962, an especially powerful Chinook in Lethbridge gusted to 171 km/h (106 mph). In Pincher Creek, the temperature rose by 41 °C (74 °F), from -19 to 22 °C (-2 to 72 °F), in one hour in 1962.[4] Trains have been known to be derailed by Chinook winds there. During the winter, driving can be treacherous, as the wind blows snow across roadways, sometimes causing roads to vanish and snowdrifts to pile up higher than a metre. Empty semitrailer trucks driving along Highway 3 and other routes in southern Alberta have been blown over by the high gusts of wind caused by Chinooks. Calgary also gets many Chinooks – the Bow Valley in the Canadian Rockies west of the city acts as a natural wind tunnel, funneling the chinook winds. In February 1992, Claresholm, Alberta hit 24 °C (75 °F) – one of Canada's highest February temperatures. Chinook winds /ʃɪˈnʊk/, or simply chinooks, are foehn winds[1] in the interior West of North America, where the Canadian Prairies and Great Plains meet various mountain ranges, although the original usage is in reference to wet, warm coastal winds in the Pacific Northwest.[2] Chinook is claimed by popular folk-etymology to mean "ice-eater", but it is really the name of the people in the region where the usage was first derived. The reference to a wind or weather system, simply "a Chinook", originally meant a warming wind from the ocean into the interior regions of the Northwest of the USA (the Chinook people lived near the ocean, along the lower Columbia River). A strong Chinook can make snow one foot deep almost vanish in one day[citation needed]. The snow partly melts and partly evaporates in the dry wind. Chinook winds have been observed to raise winter temperature, often from below -20 °C (-4 °F) to as high as 10-20 °C (50-68 °F) for a few hours or days, then temperatures plummet to their base levels. The greatest recorded temperature change in 24 hours was caused by Chinook winds on January 15, 1972, in Loma, Montana; the temperature rose from -48 to 9 °C (-54 to 48 °F). Sunset or sundown, is the daily disappearance of the Sun below the western horizon as a result of Earth's rotation. The time of sunset is defined in astronomy as the moment when the trailing edge of the Sun's disk disappears below the horizon.[1] Near to the horizon, atmospheric refraction causes the ray path of light from the Sun to be distorted to such an extent that the Sun’s disk is already about one diameter below the horizon when sunset is observed. Sunset is distinct from dusk, which is the time at which the sky becomes completely dark, which occurs when the Sun is approximately eighteen degrees below the horizon. The period between sunset and dusk is called twilight. Locations north of the Arctic Circle and south of the Antarctic Circle experience no sunset or sunrise at least one day of the year, when the polar day or the polar night persists continuously for 24 hours. Sunset creates unique atmospheric conditions such as the often intense orange and red colors of the Sun and the surrounding sky.
