Foehn wind Foehn wind A föhn or foehn (, ) is a type of dry, warm, down-slope wind that occurs in the lee (downwind side) of a mountain range. It is a rain shadow wind that results from the subsequent adiabatic warming of air that has dropped most of its moisture on windward slopes ("see" orographic lift). As a consequence of the different adiabatic lapse rates of moist and dry air, the air on the leeward slopes becomes warmer than equivalent elevations on the windward slopes. Föhn winds can raise temperatures by as much as 14 °C (25 °F) in just a
The Weather Network introduced new local weather products including an hourly forecast for the next 12 hours in 2006, long term precipitation forecasts in 2008 and improved satellite and radar maps in 2009. In 2009, The Weather Network was granted 9(1)("h") must-carry status by the CRTC, under the condition that Pelmorex develop a "national aggregator and distributor" of localized emergency alert messages. In early 2013, The Weather Network launched regional feeds, currently for Alberta and the Maritime provinces. Each feed features its own regional forecasts, weather stories, and where available, traffic information was provided by Beat the Traffic. On December 8, 2014, The
