Sentences with phrase «seasonal changes in surface temperatures»

For example, Kosaka and Xie showed than when the El Niño - related changes in Pacific ocean temperature are entered into a model, it not only reproduced the global surface warming over the past 15 years but it also accurately reproduced regional and seasonal changes in surface temperatures.

Not exact matches

This seems to be associated with particular patterns of change in sea surface temperature in the Atlantic and Pacific oceans, a teleconnection which is well - captured in climate models on seasonal timescales.

The lapse rate within the troposphere is largely determined by convection, which redistributes any changes in radiative heating or cooling within the troposphere + surface so that all levels tend to shift temperature similarly (with some regional / latitudinal, diurnal, and seasonal exceptions, and some exceptions for various transient weather events).

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

Type 3 downscaling is applied, for example, for seasonal forecasts where slowly changing anomalies in the surface forcing (such as sea surface temperature) provide real - world information to constrain the downscaling results.

The initial changes in temperature during this period are explained by changes in the Earth's orbit around the sun, which affects the amount of seasonal sunlight reaching the Earth's surface.

Due to the much higher heat capacity of soil relative to air and the thermal insulation provided by vegetation and surface soil layers, seasonal changes in soil temperature deep in the ground are much less than and lag significantly behind seasonal changes in overlying air temperature.

The amplitude of seasonal changes in soil temperature on either side of the mean earth temperature depends on the type of soil and depth below the ground surface.

The scatter diagrams described and presented on these pages depict projected changes in seasonal surface air temperature and precipitation for three 30 - year periods (2010 - 2039, 2040 - 2069 and 2070 - 2099) relative to the baseline period 1961 - 1990 in 32 sub-continental scale regions (see below).

Scatter plot of simulated springtime Δαs / ΔTs values in climate change (ordinate) vs simulated springtime Δαs / ΔTs values in the seasonal cycle (abscissa) in transient climate change experiments with 17 AOGCMs used in this report (Δαs and Ts are surface albedo and surface air temperature, respectively).

Given the intimate connection between river water and widespread alluvial aquifers it is clear that there must be stong seasonal change in «shallow groundwater» temperature many metres below the surface.
