Precipitation observations over land show the expected general increase of
precipitation poleward of the subtropics and decrease at lower latitudes [1], [26].
«If a poleward displacement of the mid-latitude storm tracks also occurs, this will shift mid-latitude
precipitation poleward, impacting regional agriculture, economy, and society.»
Not exact matches
Widening of the tropics would also probably be associated with
poleward movement of major extratropical climate zones due to changes in the position of jet streams, storm tracks, mean position of high and low pressure systems, and associated
precipitation regimes.
Their abstract says «energy budget calculations show that
poleward atmospheric energy transport increases more in solar forcing compared to equivalent CO2 forcing simulations, which is in line with the identified strong increase in large - scale
precipitation in solar forcing scenarios.»
So the emphasis shifted to
poleward shift of climate zones with particular emphasis on rain and desert belts moving such that agriculture is disrupted by great changes in
precipitation patterns.
Ozone depletion in the late twentieth century was the primary driver of the observed
poleward shift of the jet during summer, which has been linked to changes in tropospheric and surface temperatures, clouds and cloud radiative effects, and
precipitation at both middle and low latitudes.
Clouds and often
precipitation occur on the
poleward sides of both warm and stationary fronts and whenever tropical air reaching the latitude of the polar front is forced upward over the colder air near the surface.
The proximal cause of the
precipitation deficits was the recurring
poleward deflection of the cool - season storm track by a region of persistently high atmospheric pressure, which steered Pacific storms away from California over consecutive seasons (8 ⇓ ⇓ — 11).
The expansion of the tropical belt that we attribute to black carbon and tropospheric ozone in our work is consistent with the
poleward displacement of
precipitation seen in these models.
