A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth.
[2] [3] [4] Two quantitative measurements of these drivers have been proposed to identify marine heatwave, mean sea surface temperature and sea surface temperature variability. [25] [2] [4] At the local level marine heatwave events are dominated by ocean advection, air-sea fluxes, thermocline stability, and wind stress. [2]
Named heat waves are warm weather events that have been designated with a nickname due to their historical significance. Extreme heat is recognized as a natural phenomenon that poses severe risks to human health , and the likelihood of such incidents has increased due to the effects of climate change .
A new study has revealed that a marine heat wave caused a massive die-off of common murres around Alaska between 2014-2016. Biologists say the tuxedo-styled birds dive and swim in the ocean to eat ...
Siberia heat wave: A Russian heat wave smashed an all-time record high in one Siberian town on June 20, reaching a scorching 38 °C (100 °F) possibly the hottest temperature on record so far north in the Arctic, continuing an off-the-charts warm year in what is typically one of coldest places on Earth. If that reading is found to be correct ...
The increase of both ocean surface temperature and deeper ocean temperature is an important effect of climate change on oceans. [11] Deep ocean water is the name for cold, salty water found deep below the surface of Earth's oceans. Deep ocean water makes up about 90% of the volume of the oceans. Deep ocean water has a very uniform temperature ...
A definition based on the Heat Wave Duration Index is that a heat wave occurs when the daily maximum temperature of more than five consecutive days exceeds the average maximum temperature by 5 °C (9 °F), the normal period being 1961–1990. [9] The same definition is used by the World Meteorological Organization. [10]
