WebMar 31, 2012 · Despite the warming caused by the air sinking down from the mountains, the Bora is still a cold wind because the air was so chilly and dry to begin with before crossing the Rockies. Bora winds are often caused by a strong cold front passing over Colorado from the northwest. After the front passes, the winds can reach speeds of 50-60 mph. WebLocal winds occur on a small spatial scale, their horizontal dimensions typically several tens to a few hundreds of kilometres. They also tend to be short-lived lasting typically several hours to a day. There are many such winds around the world, some of them cold, some warm, some wet, some dry. There are many hazards associated with the winds.

WebThe fast, hot winds cause vegetation to dry out, increasing the danger of wildfire. Once the fires start, the winds fan the flames and hasten their spread. The winds create turbulence and establish vertical wind shear (in which winds exhibit substantial change in speed and/or direction with height), both posing aviation hazards.

WebFirst, a downsloping flow produces adiabatic warming. Air warms at the dry adiabatic lapse rate as it sinks. This should cause temperatures to warm and heights to RISE (thermal expansion). Second, a downsloping wind is associated with stability (RH decreases, downward vertical velocities).
