Sentences with phrase «hiatus period»

In many simulation runs of continued warming hiatus periods arose of at max a decade.

«Nevertheless, neither data set supports the model result of Meehl et al. that the heat uptake in this layer (300 - 700m) in the Pacific dominates over other ocean basins during hiatus periods.»

This is supported by historic observations (Figure 1), which shows roughly decade - long hiatus periods in upper ocean heat content during the 1960s to 1970s, and the 1980s to 1990s.

I'm wondering if anyone has collected the model runs with long hiatus periods in them and looked for commonalities... for example extended periods of La Ninas or anything else.

These very different fingerprints in energy flow between atmospheric radiative forcing and internal ocean circulation processes make it possible to attribute the cause of a climate hiatus period.»

They relate the current hiatus period at the surface and a deeper penetration of the warming into the ocean with changes in the trade winds on the subtropical Pacific (intensification).

Does someone known if a similar intensification of the trade winds took place during the 1960s explaining then that hiatus period too?

Figure 8 presents model - data trend comparisons for the two warming periods since 1914 and the warming hiatus period from 1945 to 1975.

Through this lens a study by Amaya et al. (2015) focuses on identifying equatorial Pacific changes during the transition from a non-hiatus period (pre-1999) to the present hiatus period (post-1999) using a combination of reanalysis and observed datasets.

This means — as the NCAR model shows — that during hiatus periods the deep ocean could warm 18 percent more, simultaneous with 60 percent less warming in the upper ocean.

to attempt to explain the data during surface temperature hiatus periods that contradict the projected anthropogenic GHG warming!

«Fifteen - year - long hiatus periods are common» in both historical records and in computer models, the technical summary says.

«The paper makes a convincing case for the importance of Pacific processes that can make major contributions to hiatus periods,» said NCAR's Meehl.

If our emissions peak by 2040, the temperature rise will slow by 2100, and hiatus periods will become more likely.

«The implication is that we will get fewer hiatus periods, or hiatus periods that last for a shorter period,» says Wenju Cai at CSIRO in Melbourne, Australia, who wasn't involved in the work.

Previously, the drawdown of heat by the Equatorial Pacific Ocean over the hiatus period, due to cool sea - surface temperatures associated with a succession of cool - surface La Nina episodes, was thought to be sufficient to explain the hiatus.

Professor Sybren said: «It can be excluded, however, that this hiatus period was solely caused by changes in atmospheric forcing, either due to volcanic eruptions, more aerosols emissions in Asia, or reduced greenhouse gas emissions.

Both are based on annual mean values.The temperature for the hiatus period is highlighted.

The model provides a plausible depiction of processes in the climate system causing the hiatus periods, and indicates that a hiatus period is a relatively common climate phenomenon and may be linked to La Niña - like conditions.

The general pattern of warming and ocean circulation in the model, during these hiatus periods, is very similar to that which occurs over shorter timeframes in the La Niña phase of ENSO.

There have been decades, such as 2000 — 2009, when the observed globally averaged surface - temperature time series shows little increase or even a slightly negative trend1 (a hiatus period).

Meehl et al., 2011 (doi: 10.1038 / NCLIMATE1229) show that with a similar radiative imbalance, hiatus periods and non-hiatus periods can occur, and that in the first case larger heat storage in the deep ocean takes place.

And another question, why is the hiatus period during the 1960s not reflected in a larger heat storage in the deep ocean?

The general pattern of sea surface temperature during these hiatus periods is very reminiscent of a La Niña - like climate state.

The comparisons for the full 1979 to 2012 term of the Cowtan and Way (2013) are in the left - hand graphs and the «hiatus period» of 1997 to 2012 are shown in the right - hand graphs.

Both versions of the Cowtan and Way (2013) data have slightly higher long - term (1979 - 2012) warming rates than HADCRUT4, but they have much higher warming rates than HADCRUT4 during the hiatus period of 1997 - 2012.

And one rather surprising result they found were «Hiatus periods».

And the models predict that these Hiatus periods last for a decade or so.

For example, Figure 7 illustrates the warming and cooling rates of the HADCRUT4 data, and as a reference, the GISS LOTI data, for the period of January 1997 to December 2012... the hiatus period.

«Model - Based Evidence of Deep - Ocean Heat Uptake During Surface - Temperature Hiatus Periods.»

«The hiatus period gives scientists an opportunity to understand uncertainties in how climate systems are measured, as well as to fill in the gap in what scientists know,» Yan said.

This close agreement in the trend of the corrected ship data indicates that these time dependent ship adjustments did indeed correct an artifact in ship data impacting the trend over this hiatus period.»

«The hiatus period gives scientists an opportunity to understand uncertainties in how climate systems are measured, as well as to fill in the gap in what scientists know,» Yan said in a statement.

«the progressive increase in buoy numbers over time between 1990 and 2012 is responsible for skewing the SST trend upwards during the hiatus period.»

«If an El Niño event is on the way, the hiatus period may be coming to a close,» writes Palmer in his report.

15 - year - long hiatus periods are common in both the observed and CMIP5 historical GMST time series (see [Figure 9.8] and also Section 2.4.3, Figure 2.20; Easterling and Wehner, 2009, Liebmann et al., 2010).
