The atmosphere has no heat storage memory but the ocean does

 

  • A number of model studies show increases in warming over land are due to warming in the oceans and subsequent transport of heat over land rather than through direct radiative forcing (Compo and Sardeshmukh, 2009;Lambert et al., 2011;Geoffroy et al., 2015). If ocean warming due to radiative forcing is compared to direct increases in sea surface temperature, the warming over land is little different (Dommenget, 2009). This ocean–land effect is much greater than the land–ocean effect, where increasing temperature over land has little effect on the ocean (Dommenget, 2009; Lambert et al., 2011). The oceans are estimated to contribute 80– 90% of the warming on land in one estimate (Dommenget, 2009) with horizontal energy transport contributing 70% in another (Geoffroy et al., 2015). Uncoupling transport between land and ocean leads to little warming for either, showing it is the coupled relationship between the two that is important (Lambert et al., 2011).

    If ocean surface warming is gradual, the land response will be gradual, but if warming arises out of nonlinear interactions between the ocean and atmosphere (involving land as per the coupled transport process above) nonlinear warming on land would follow almost immediately, perhaps driven by the processes described by Reid and Beaugrand (2012). Under this hypothesis, decadal climate regime change arising out of ocean‐atmosphere interactions is capable of producing step changes in mean sea surface temperature. Consequently, these step changes could be transmitted to adjacent continental areas and/or though teleconnections. The atmosphere has no heat storage memory but the ocean does. If the added heat energy trapped by anthropogenic greenhouse gases follows the same path as natural heat energy trapped by naturally occurring greenhouse gases, the interaction of external forcing with internal variability is a logical result.

    The atmosphere has no heat storage memory but the ocean does.”

    It’s not expected to store it. It does remember it has more CO2 in it, so it remembers to retain it longer. We can say that’s still storage, just weak storage. The oceans remember the climate from centuries ago. The Antarctic land ice remembers further back with its mass. The land temperatures depend on what the ocean SST is and how much volume of the near surface atmosphere crosses from oceans to land.

    Uncoupling transport between land and ocean leads to little warming for either, showing it is the coupled relationship between the two that is important (Lambert et al., 2011).”

    Why? The oceans if they don’t transport, just reabsorbs the warmth with their massive thermal capacity or it goes TOA. And the atmosphere over land doesn’t even have the storage to hold onto the additional warmth after raising the average temperature something small but still material and real. It is fed by ocean warmth for sustained material increases.

    Now back to my rigid jet stream theory. West to East flow from the Pacific to the Americas. From the Atlantic to the Europe and Africa. The rigid jet is a warming planet. With good traction in the hemisphere’s Winter. The wavy jet loses West to East transport. Tsonis 2007 talked about a wave 2 and wave 3 anomaly at the beginning of that paper which I interpreted a rigid (2) and wavy (3) jet stream.
