Phenomena of sudden changes of water temperature in the coastal waters: comparison of upwelling events of Lake Baikal and Japanese lakes and coastal oceans
AbstractIt has been known that, during the thermally stratified period, the water temperature in the coastal areas of Lake Baikal sometimes drops drastically, by several to ten degrees within only a few hours, and stay cold for a few days or more. In the recent quarter centuries, intensive observations have revealed such significant phenomena are related to the coastal upwelling event that is not rare, but rather common (seen several times every summer) in this great lake (Tanaka et al., 2005; Troitskaya et al., 2015). As similar phenomena exist in some other waters in the world, we here show a few examples from Japanese lakes and coastal waters.
