Severe thunderstorms require high CAPE values and the higher the CAPE value, the more energy available to promote thunderstorm growth. However, the CAPE variable is not a “magic number” that will predict the certainty of a thunderstorm.
How to tell if barometric pressure is changing?
Use an altimeter on a GPS unit to figure out atmospheric pressure in the field. If you check the altimeter and it shows an elevation change when you have not moved, then the pressure is changing. If the altimeter shows a rise in elevation, the barometric pressure is falling and a low-pressure system is on its way.
Why do we have westerly winds?
Because the prevailing winds in the United States are westerly winds, low-pressure systems or storms move to the east, bringing southerly winds on their outer edges. Do not, however, be deceived by localized winds in valleys or off mountains, since they are usually caused by heating and cooling during the day.
What are the long smooth clouds that indicate high winds in the upper atmosphere?
Lenticular clouds , also called wave clouds, are long smooth cloud formations that indicate high winds in the upper atmosphere. Lenticular clouds typically form over mountains and mountain ranges when the wind is forced upward as it reaches the mountain's windward side.
What is the wind on a mountain?
The upward wind curls above the mountain, forming the lenticular cloud on the leeward side of the mountain crest. A localized low-pressure system often builds on the leeward side of the mountain. While the clouds appear stationary, they often indicate a larger incoming storm.
Why are high clouds so warm?
These high clouds often indicate incoming storms . They also act as insulators, keeping the night warm and blocking heat from escaping into the atmosphere. If the stratus clouds are combined with southerly winds, the night can be very warm.
