How will climate change affect the grasslands biome?
the global climate patterns of temperature and precipitation generated by atmospheric circulation cells described in chapter 2 provide a basis for understanding the geographic distribution of biomes described in chapter 3. the transition from the wet tropics to the seasonal temperate biomes seen in figure 3.5a in your textbook results in large part from the hadley cells (see figure 2.7 in your textbook). ascending air in the atmosphere generates the storms and high precipitation of the tropics, while the descending air at the northern and southern edges creates dry, hot desert zones. what would happen if the hadley cells expanded in size and reached further north and south? this question has been examined by atmospheric scientists who have noted such a shift over the past several decades (heffernan 2016). the cause for the observed shift is uncertain, but may include climate change, loss of ozone in the stratosphere, or natural climate cycles. while the reason(s) for the observed expansion of the hadley zone is/are not known, climate change is predicted to cause continued expansion over the next century.
question 1.how would you expect the area and geographic locations of the tropical rainforest, tropical seasonal forest, and desert biomes to change if the hadley cells expanded north and south?
