Exercise controls weight. � Exercise can help prevent excess weight gain or help maintain weight loss. The orographic effect is also known as the Foehn effect and orographic precipitation or relief rainfall, although these two terms only comprise a part of the process. Please explain your reasoning relating it to what you have learned AND the mountain ranges that you draw in the next question (question 5). During the WES Exercise, forecasters were asked to make a 24 hour QPF forecast beginning at 4 PM on Tuesday afternoon ... dynamics, the south to southeast winds at the low levels would tend to add an orographic component to the rainfall enhancement. The dramatic variation in altitude over a short distance has resulted in pronounced orographic effects, effects which severely limit our ability to explain precipitation dynamics in Nepal. Another complication is that the data set required to explain the processes is limited. � As a result, the rainfall is minimal. Here we will explore how the orographic effect influences (or not) precipitation patterns in the western US. � Beyond the Highlands, the effect of these winds gets reduced. 328 0 obj <> endobj When air is forced to rise, its temperature will decrease; and if air subsides, its temperature will increase. (2000), 126, pp. Exercise - Exercise - Health effects of exercise: The greatest benefit of a regular exercise program is an improvement in overall fitness.
