專題討論

(Seminar)

授課老師: 游政谷

Seminar(3)


高雲(seeder cloud)

低雲 (feeder cloud)


2. Upslope condensation

(上坡風凝結機制)


Low-level PPI of radar reflectivity

Orographic Rainband(OR)

--- Quasi-stationary

--- Orientation closely linked to the terrain feature

Typhoon Rainband(TR)

--- Fast movement

--- Curved feature

dBZ


3. Upslope triggering

(上坡風激發機制)



UT

UT

NCFR


4. Upstream triggering

(上游減速激發機制)




5. Thermal triggering

(熱力激發機制)


中午時刻在山脊附近發展的積雲

(攝於宜蘭省道,雪山山脈南側)


6. Lee-side triggering

(背風面激發機制)


在較小的Froude number環境下, 美國華盛頓州奧林匹克山背風面之輻合 (Mass 1981)


7. Lee-side enhancement by gravity waves

(透過重力波在背風面的加強機制)
