Sentences with phrase «tropospheric temperatures over land»

Satellites have particular difficulty accurately measuring tropospheric temperatures over land.

Not exact matches

The IPCC found that: Over the Northern Hemisphere land areas where urban heat islands are most apparent, both the trends of lower - tropospheric temperature and surface air temperature show no significant differences.

Ocean temperatures are rising slower than over land, therefore even if tropical land tropospheric temperatures were being set by a moist adiabat over the ocean, it would still have a smaller ratio with respect to the land temp.

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.

Based on the understanding of both the physical processes that control key climate feedbacks (see Section 8.6.3), and also the origin of inter-model differences in the simulation of feedbacks (see Section 8.6.2), the following climate characteristics appear to be particularly important: (i) for the water vapour and lapse rate feedbacks, the response of upper - tropospheric RH and lapse rate to interannual or decadal changes in climate; (ii) for cloud feedbacks, the response of boundary - layer clouds and anvil clouds to a change in surface or atmospheric conditions and the change in cloud radiative properties associated with a change in extratropical synoptic weather systems; (iii) for snow albedo feedbacks, the relationship between surface air temperature and snow melt over northern land areas during spring and (iv) for sea ice feedbacks, the simulation of sea ice thickness.

But let's look at the long - term NOAA record of tropospheric specific humidity and compare this with the HadCRUT globally and annually averaged land and sea surface temperature anomaly over the same period:
