Let's compare the warming and cooling patterns for lower
troposphere temperatures over the oceans to a spatially complete, satellite - enhanced sea surface temperature dataset, Reynolds OI.v2.
And for the period of 1997 to 2012, there are no similarities between the warming and cooling patterns for lower
troposphere temperatures over the oceans and the satellite - enhanced sea surface temperature data.
Not exact matches
This warming can be seen in measurements of
troposphere temperatures measured by weather balloons and satellites, in measurements of
ocean heat content, sea surface
temperature (measured in situ and by satellites), air
temperatures over the
ocean, air
temperature over land.
Thus, it would be appropriate to conclude from this that short - term fluctuations in the overall upward CO2 trend are moderately well correlated with
temperatures in the lower
troposphere over oceans.
Comparison of global lower
troposphere temperature anomaly
over the
oceans (blue line) to a model based on the first derivative of atmospheric CO2 concentration at Mauna Loa (red line).
Since you are a frequent visitor to WUWT, you are well aware that I have illustrated, explained, and animated cause (ENSO) and effect (the warming of sea surface
temperatures,
ocean heat content, lower
troposphere temperatures, and land + sea surface
temperatures) in dozens of blog posts
over the past 3 1/2 years.
Over ocean stretches with a positive SST anomaly air convection is higher (as the
temperature difference between the warm sea surface and the cool air higher up in the
troposphere is greater), so a higher likelihood for the formation of depressions exists and more precipitation is to be expected.
Temperatures at the surface, in the
troposphere (the active weather layer extending up to about 5 to 10 miles above the ground), and in the
oceans have all increased
over recent decades (Figure 2.2).
Jones et al. (2003) investigated the changes in
temperature over the past 4 decades at both the near surface (
troposphere) and stratosphere layers, and compare them to changes predicted by a coupled atmosphere /
ocean general circulation model, HadCM3.
Here, we present an explanation for time - invariant land — sea warming ratio that applies if three conditions on radiative forcing are met: first, spatial variations in the climate forcing must be sufficiently small that the lower free
troposphere warms evenly
over land and
ocean; second, the
temperature response must not be large enough to change the global circulation to zeroth order; third, the
temperature response must not be large enough to modify the boundary layer amplification mechanisms that contribute to making φ exceed unity.
