Often rendered on unusually shaped canvases with paint layered so thick it seems three - dimensional, Murray's decision to stick with painting an a time when it had largely fallen out of favor with modern artists — along with her choice to ignore many of painting's traditional boundaries and labels — helped her to stand out.

Mean time why not study boundary layers while having fun with a good mystery like the Titanic?

The oceanic boundary layer (the thermocline), with its much more vast reservoirs of heat, operates on much longer time scales.

GCMs have a terrible time in resolving the physics of the stable boundary layer.

Changes in land surface properties as the wet season progresses impact surface fluxes and boundary layer evolution on daily and seasonal time scales that feed back to cloud and rainfall generation.

It is a convective layer on global circulation time scales, just like the boundary layer is convective on daily time scales, so its lapse rate is defined by the processes by which air ascends and descends, namely convection.

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.
