The phrase
"seasonal cycle" refers to the pattern of changes that occur in nature over the course of a year. It includes the different seasons - such as winter, spring, summer, and autumn - and the variations in weather, temperature, and the growth and behavior of plants and animals that happen during each season.
Full definition
Like most climate - related variables, snow cover shows a
strong seasonal cycle, with more snow in winter and less in summer.
Other stations of the global CO2 measurement network show almost exactly the same; the most important regional variation is the greatly subdued
seasonal cycle at stations in the southern hemisphere.
All bands have very well defined annual cycles, i.e., every year the phase change conditions for each band goes through
clear seasonal cycles.
This statistic can be used to assess the combined contributions of both spatial pattern errors and
seasonal cycle errors.
It appears that the
overall seasonal cycle is riding on a gradually warming average value, but peak positive excursions are being limited by the ice melt temperature in Summer.
Your point «The superior utility of the
OLR seasonal cycle in narrowing the spread of climate sensitivity may arise because it is a better measure of dOLR / dTs.»
By contrast, when only the OLR
seasonal cycle predictor field is used, either in full or restricted to latitudes 30S — 30N, full standardization has only a marginal impact on the Prediction ratio.
Instead, results based on what appears to be the most appropriate choice of predictor variables — OLR
seasonal cycle over 30S — 30N latitudes — indicate a negligible (3 %) increase in mean predicted warming, and on their face support a greater narrowing of the range of predicted warming.
Model performance in reproducing the
observed seasonal cycle of land snow cover may provide an indirect evaluation of the simulated snow - albedo feedback under climate change.
After its latest battle with H1N1, a U.S. Centers for Disease Control and Prevention committee recommended in February that everyone six months and older get the annual vaccine, a step that should improve immunity against future pandemics as well
as seasonal cycles of the flu.
Simulations of the mid-Holocene with AOGCMs (see Section 9.2.1.3 for forcing) produce an amplification of the
mean seasonal cycle of temperature of approximately 0.5 °C to 0.7 °C.
Meanwhile, permafrost observers the world over will take measurements in boreholes at least 30 meters (100 feet) deep — the depth where temperatures do not fluctuate
during seasonal cycles — though some will stretch much deeper.
The persistent nature of the hexagon in imaging observations implies that it is present throughout Saturn's 29 -
year seasonal cycle.
And some diseases that spread among people might turn out to be nearly impossible to predict using satellite and environmental data beyond what researchers already know
about seasonal cycles, like that for the seasonal flu.
Each species seems to be tied to their
local seasonal cycle of greening, which is markedly different among species, suggesting that annual climate cycles may help maintain genetic and phenotypic divergence in giraffes.
At first, both groups of starlings appeared to behave normally, exhibiting a
natural seasonal cycle in which «the whole [brain] mechanism for song shuts down in autumn, presumably to make room for other centers that are more important — like finding food,» says Katherine Buchanan, a study leader.
The area has a
predictable seasonal cycle, where the water rises and descends, with average changes of about 35 feet during the course of the year.
Hall, A. & Qu, X. Using the
current seasonal cycle to constrain the snow albedo feedback in future climate change.
Eisenman, I., T. Schneider, D. S. Battisti, and C. M. Bitz, 2011: Consistent changes in the sea
ice seasonal cycle in response to global warming.
A least - squares fit regression line for the simulations (solid line) and the observed
seasonal cycle Δαs / ΔTs value based on ISCCP and ERA40 reanalysis (dashed vertical line) are also shown.
Already this is not my understanding of a climatology as I understood it to include the
expected seasonal cycle, e.g. the file abstem3 in the HadCRUT3 dataset.
«And what we found was that we got the right kind of temperature change and we got a
dampened seasonal cycle, both of which are things we think we see in the Pliocene.»
For example, if at the end of this exercise I find that hey, I really didn't NEED that many skirts... I may cut down on my skirt selection and instead add an additional shirt / jean / dress
next seasonal cycle.
Models are compared primarily to the current climatology and all of the adjusting goes into getting the mean climate /
seasonal cycle etc. correct.
Global values are not particularly useful since they conflate the two disparate and out of
phase seasonal cycles.
Here we show the existence of a
distinctive seasonal cycle of subsurface cooling via mixing in the equatorial Pacific cold tongue, using multi-year measurements of turbulence in the ocean.
