ATSC 113 SNOW questions with complete solution 2024High pressure - correct answer also known as a high pressure system or an anticyclone, is a region where pressure is higher than in surrounding regions (includes bluebird powder days, bluebird spring skiing days, best glacier travel days) Isobars - correct answer are lines, or contours, connecting locations that have the same pressure. - can be used to indicate high pressure centres and low pressure centres. ridges - correct answer The centre, or axis, of the ridge is indicated by a squiggly line. Ridges are areas of relatively high pressure that extend out from high pressure centres. In a ridge, the isobars do not form a closed circle, but rather partially enclose values of higher pressure. If you travel away from a ridge in most directions, pressure will decrease, but not in all directions. If you travel along a ridge towards the high pressure centre it's connected to, pressure will increase towards the high pressure centre. They are visible on pressure maps as "kinks" in the isobars pointing away from the high pressure centre. On a topographical map, pressure ridge is equivalent to a mountain ridge. why does high pressure bring good weather? - correct answer Pressure differences are typically fairly weak under high pressure, so winds tend to be lighter. Flat light - correct answer Increasing high clouds (with the approach of a low pressure system) can lead to flat light, where the clouds diffuse the light, and the snow surface no longer has any definition. air pressure - correct a
