The winter cycles of flu in temperate regions are due to the big,
consistent changes in humidity and temperature.
Not exact matches
Total column water vapour has increased over the global oceans by 1.2 ± 0.3 % per decade from 1988 to 2004,
consistent in pattern and amount with
changes in SST and a fairly constant relative
humidity.
The observed regional
changes are
consistent in pattern and amount with the
changes in SST and the assumption of a near - constant relative
humidity increase
in water vapour mixing ratio.
Although,
in the tropics, glacier mass balance responds sensitively to
changes in precipitation and
humidity (see Lemke et al., 2007, Section 4.5.3), the fast glacier shrinkage of Chacaltaya is
consistent with an ascent of the 0 °C isotherm of about 50 m / decade
in the tropical Andes since the 1980s (Vuille et al., 2003), resulting
in a corresponding rise
in the equilibrium line of glaciers
in the region (Coudrain et al., 2005).
The short and lazy answer to Matthew Marler's question about the column energetics that bring the system back to equilibrium is that GCMs do of course represent evaporation, sensible heating, etc
in ways that are undoubtedly imperfect (e.g., via «bulk formulas» that transfer energy down - gradient of temperature or
humidity differences between the surface and air aloft), but they are free to evolve
in climate
change scenarios
in ways that are physically self -
consistent.
