It is more efficient in the winter to draw heat from
the relatively warm ground than from the atmosphere where the air temperature is much colder, and in summer transfer waste heat to the relatively cool ground than to hotter air.
Not exact matches
On the contrary, roughly 80 percent of HOT is devoted to on - the -
ground reporting that focuses on solutions — not just the
relatively well known options for reducing greenhouse gas emissions and otherwise limiting global
warming, but especially the related but much less recognized imperative of preparing our societies for the many significant climate impacts (e.g., stronger storms, deeper droughts, harsher heat waves, etc.,) that, alas, are now unavoidable over the years ahead.
It is true, however, that most heavy snowfalls occur with
relatively warm air temperatures near the
ground — typically 15 °F or
warmer since air can hold more water vapor at
warmer temperatures.»
The
ground and particularly the subsoils can be
relatively warm.
Still air with either little vertical shear and
relatively weak
warming of the
ground or with so much vertical shear that turbulence occurs and irreversibly physically mixes the air parcels faster than «reversible» adiabatic expansion can keep up favors the «isothermal» pole, although this too is almost never precisely observed.
Wouldn't
relatively - small, easily - refueled, modular nuclear generators, sited below
ground near point of use and augmented with rooftop solar in
warm climes, enable «mini-grids» to power sub-communities and small towns without extensive transmission lines?
For instance, if a particular sector has been shown to potentially experience ocean
warming in the future — one of the main triggers to
grounding line retreat — we would assign a
relatively high probability; while a sector already experiencing
grounding line retreat would have a very high probability.
1 km above the surface
warms much more than the tropopause, closer to the surface is convectively coupled to the
relatively stable
ground.
Being below
ground level, the temperature seldom fluctuated, staying
relatively warm.
