Sentences with phrase «average seasonal cycle»

All it is the correlation of the seasonal cycle with the long term average seasonal cycle.

As I read it, the W (weather) function would not only include weather, as I would normally understand it, but the difference between the local seasonal cycle and the globally averaged seasonal cycle.

Not exact matches

Those expectations are based on analysis of historical precedence, including the average market gains in the third year of the presidential election cycle, strong momentum, earnings growth, seasonal trends, accelerating economic growth, and the normal market performance around the first Fed rate hike.

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.

TOA radiation anomalies are determined from monthly averages by removing the seasonal cycle then smoothing with a twelve - month running mean.

Tuning to the seasonal cycle, or to the climatological average, or to the variance of some field — which can be well characterised from observations, is different to tuning to a transient change of over time — which is often less well known.

(57m) However, externally imposed forcings with a global average externally imposed RF may tend to cause similar climatic responses both in the global average and in regional / latitudinal and seasonal (modulation of response to external - forcing cycles that themselves are held constant) and internal variability patterns, provided they are not too idiosyncratic.

And, that just coincidently, the rate of the rise has consistently been (when averaged over a few year period to smooth out variability due to seasonal cycles and other factors) equal to about half of the emissions of CO2 that we are putting into the atmosphere?

Also, just because the average pole - to - equator temperature gradient is decreasing doesn't mean that the seasonal variation won't still be in place, and then there's the whole issue of the hydrologic cycle intensification — a moister atmosphere carries more latent heat and thus may generate more intense mid-latitude storms as well.

• Solar generating capacity continues to be rolled out, as costs decline expanding to supply the seasonal maximum of daily average, with pumped hydro to provide daily balancing until superior technologies come on - line, and open - cycle gas turbines shifting to a purely back - up function, with consequent substantial reductions in overall fossil CO2 emissions.

Third, the ice core data how conclusively that, during natural climate cycling, changes in temperature precede changes in carbon dioxide by an average 800 years or so (Fischer et al, 1999; Indermuhle et al, 2000; Mudelsee, 2001; Caillon et al, 2003); similarly, temperature change precedes carbon dioxide change, in this case by five months, during annual seasonal cycling (Kuo, Lindberg and Thomson, 1990).

Any change in CO2 levels should be calculated from calendar year averages or 12 month moving averages to remove the seasonal cycle.

The global amplitude of the seasonal cycle globally is 3.5 K (which I think is a hemispheric average about 10 K of warming in the NH and -3 K of «warming» in the SH).

I don't think he did anything with cloud height or cloud cover, so I'm confused by your question, but either way the plots reflect monthly global average data with a 12 running mean applied to smooth out the seasonal cycle.

Meanwhile, the global average, after controlling for the seasonal cycle, popped above 400ppm late last year.

Is there a diurnal or seasonal cycle or is this averaged out as well?

In reality each end of a full seasonal cycle (as good as near each monthly average compared to the previous year) ends higher than the start of the same seasonal cycle.

Seems unlikely to make much difference over large scale averages but wouldn't this be a potential problem for accurate reproduction of more intricate details like seasonal or diurnal cycles in individual grid cells or regions?

Seasonal cycle Δαs / ΔTs values are the difference between 20th - century mean April and May αs averaged over Northern Hemisphere continents divided by the difference between April and May Ts averaged over the same area and time period.

The latter is determined as a moving average of SEVEN adjacent seasonal cycles centered on the month to be corrected, except for the first and last THREE and one - half years of the record, where the seasonal cycle has been averaged over the first and last SEVEN years, respectively.

There is a seasonal cycle in global mean temperature which means that on average, July and August are roughly 3.6 ºC (6.5 ºF) warmer than December and January.

In making their seasonal outlook, which was released on May 23, NOAA cited a broad area of above - average sea surface temperatures in the North Atlantic Basin, a continuation of a natural cycle of above - average hurricane activity, and a lack of an El Niño event in the Pacific Ocean as reasons why there may be more storms this year.
