Weather Patterns
 Weather types that are all ocean-based wind
currents that are just called different terms
based on region
 ”tropical cyclone" (the Indian Ocean)
 "hurricane" (the North Atlantic Ocean, the
Northeast Pacific Ocean east of the
dateline, or the South Pacific Ocean east of
160E)

 Weather types that are all ocean-based wind
currents that are just called different terms
based on region
 ”tropical cyclone" (the Indian Ocean)
 Part of summer monsoon season
 Destroy farmland and wipe out villages
Tsunamis
 Triggered by intense underwater earthquake
 Large, fast moving ocean waves cause by
underwater disturbance
 Waves slow down in shallow water, causing
a rapid rise in water levels
Physical Impact of Extreme
Weather
 Rains are critical to the agriculture of
the region
 Nourish rain forests, irrigate crops, produce
floodwaters
 Droughts come with winter monsoons
 Lush landscapes become arid wastelands
quickly
Economic Impact of Extreme
Weather
 Floods and droughts ruin crops
 Many mouths to feed- Sometimes South Asia must
resort to buying food for the citizens
