Why is the average cloud cover on mid latitudes increasing to the poles?
5 answers
The increase in average cloud cover from mid latitudes towards the poles can be attributed to various factors. Studies show that cloud cover over land areas has decreased while cloud cover over ocean areas, especially towards the poles, has increased. Additionally, the presence of Polar Mesospheric Clouds (PMCs) has been observed to extend from midlatitudes to the poles, with higher ice concentrations in the Northern Hemisphere compared to the Southern Hemisphere. Furthermore, changes in vegetation cover in the northern midlatitudes can influence local climate responses nonlinearly, affecting cloud feedback mechanisms. These combined factors contribute to the observed trend of increasing cloud cover towards the poles from mid latitudes.
