Sentences with phrase «relative polar warming»

As this relative polar warming increased during February, the NASA maps show that colder than normal temperatures expanded over North America through Canada and parts of the Northern U.S. even as a cold spell began to blossom in Europe.

Not exact matches

The team's data show that during the polar night, indoor heating can bleed into the environment, warming it by as much as 10 degrees Celsius relative to nearby rural sites.

For example, they predicted the expansion of the Hadley cells, the poleward movement of storm tracks, the rising of the tropopause, the rising of the effective radiating altitude, the circulation of aerosols in the atmosphere, the modelling of the transmission of radiation through the atmosphere, the clear sky super greenhouse effect that results from increased water vapor in the tropics, the near constancy of relative humidity, and polar amplification, the cooling of the stratosphere while the troposphere warmed.

Polar amplication is of global concern due to the potential effects of future warming on ice sheet stability and, therefore, global sea level (see Sections 5.6.1, 5.8.1 and Chapter 13) and carbon cycle feedbacks such as those linked with permafrost melting (see Chapter 6)... The magnitude of polar amplification depends on the relative strength and duration of different climate feedbacks, which determine the transient and equilibrium response to external forcings.

The increase in relative humidity is due to warmer surface sea temperatures allowing greater evaporation and warmer polar conditions causing less condensation.

With polar regions excluded, 2017 becomes the third warmest year, and the «global» warming relative to the base period is reduced by almost a tenth of a degree Celsius.
