a) Briefly outline the steps of how higher temperatures can also cause stronger hurricanes and increased flooding

Answer 1

@ Outline in steps of higher demperature cau Ccause hurricanes, and increase in floud's ① Due to several causes like global warming earth atmosphasic semperature increases. 29 with increase in temperature above sea. it increases the precibidation of warm sea water 3 The atmosphere can move hold more moisture with merease in temperature and become more unstable. 4) with increase in more Warm; moist air over Oceans mises ubward from see it increases more moist energy cunstable) and with increase the energy greater the wind shear and cause hewricanes.. ② Also , warming temperature in almosthese causes more evaporation, meaning more .. water is amallable for precipitatione for every lar murease in atmospheric temperature atmosphere can hold around 4% more water vapour, which ! lead heavier rain and increase risk of flooding of rivers and streams.
