Abstract
Observations indicate that some squall line systems moving from the Taiwan Strait towards the mountains would decrease in intensity and dissipate. Obviously the terrain effects on the squall lines are very important. A two-dimensional terrain following coordinated cloud model was used to study geographical effects on a squall line. In the model the mountain peak was assumed to be 1 or 2 km in height with the squall line forming over the plain area and propagating towards the mountains. In the plain area new convection continually formed on the forward side of the squall line so that the squall line could maintain itself. When the squall line moved over mountainous areas it slowed down and began decreasing its intensity due to the weakness of new convection. The decrease in intensity resulted from less moisture flowing into the squall line at the higher altitude. The terrain effect on the restriction of the development of the squall line was more evident the higher the mountain.
Highlights
The effects of moun七 ainous terrain on precipitation sy 的ems have been discussed very extensively in the past (S 血ith, 1979)
There are 七 hree experiments in this study name features of the three runs are shown in Fig
The difference that the width of the domain is 300 km for run cooling region that triggers the initial convection side of the domain for run A, B, and C, the initial was much closer to the mountain
Summary
The effects of moun七 ainous terrain on precipitation sy 的ems have been discussed very extensively in the past (S 血ith, 1979). Another squall line affected by mountains occurred on May This model squall line was propagated towards mountainous moun 個ins. Case was chosen for use here because were collected for a squall line occurring near mountainous areas.
