MSC 220 Lecture Notes - Lecture 17: Ocean Heat Content, Water Cycle, Northern Hemisphere
Document Summary
Pattern: warming troposphere and cooling stratosphere: upward rising temperature trend in troposphere, cooling trend in stratosphere, prove global warming is not everywhere, this is very characteristic of anthropogenic climate change. Oceans can remove heat from some surface areas. Global temperature change: only risen by 1 degree c, not a huge change by itself, but other changes can impact negatively. Impacts of warming: humidity and water vapor: very likely that global near surface and tropospheric air specific humidity have increased since 1970s, tropospheric water vapor content increased at a rate of about 7% per. Impacts of warming: precipitation: hydrological cycle intensifies, ipcc: average over the mid latitude land areas of nh precipitation has likely increased since 1901, tophat question. Find place in africa with significant drying trend. Tropical storms: no increase in the number of tropical storms experienced in na, however, there has been an increase in intensity of strong cyclones.
