Always pay close attention to the fine print in the auction description and only buy from reputable sellers with strong feedback ratings.

Not exact matches

He said the central bank's rate rise talk could restart the negative feedback loop that took place this year, when a strong dollar leaned on emerging markets currencies, including the Chinese yuan, and commodities prices, creating tight financial conditions and economic weakness.

Companies with the strongest retention rates offer training programs, provide regular feedback, recognize hard work and spend quality time with employees.

Recent observational and modelling evidence thus provides strong additional support for the combined water vapour - lapse rate feedback being around the strength found in AOGCMs.

In this particular environment, it doesn't look like there are strong negative feedbacks on erosion rates because the material appears to be simply too fine - grained and ice - rich to be redeposited locally and form barriers, bars, etc..

Finally, because of the posited strong water vapor feedback, which depends on absolute, not anomaly, temperatures, one would expect that the relationship should be positive, not negative due to the greater rate of accumulation of water vapor at higher absolute temperatures.

CH4 — yes, the rate at which, as a feedback, a C reservoir is depleted with some fraction going into the atmosphere would be relatively more impotant if more of it is as CH4; if Chuvian runaway (thanks, wili) can be achieved, to the point of exhausting some (designated portion of a) surface C reservoir, with a CH4 flux, then there would be a cooling period afterword (setting aside other slow feedbacks), and if the CH4 feedback were slowed down, then the feedback wouldn't be as strong, and perhaps the C reservoir wouldn't be exhausted unless the external forcing were larger (this being a hypothetical discussion; no assertion that it will happen).

If we isolate the ocean for diagnosis, there is a rather short list of suspect forcings and feedbacks (ie changes in shortwave reaching ocean surface possibly from strong negative aerosol feedbacks, net positive rate change in loss of longwave from the ocean (which would have implications for the positive WVF), net positive heat loss through evaporation without balancing compensation (with other implications for positive WVF).

The water vapor and lapse rate feedbacks are typically combined because models show a strong negative correlation between the two.

where it is clear that water vapour feedback is MUCH stronger and counteracts the «lapse rate» feedback.

However, the contributions of water vapour / lapse rate and surface albedo feedbacks to sensitivity spread are non-negligible, particularly since their impact is reinforced by the mean model cloud feedback being positive and quite strong.

Quoting Dr Roy Spencer: «One of the most robust feedback relationships across the IPCC climate models is that those models with the strongest positive water vapor feedback have the strongest negative lapse rate feedback (which is what the «hot spot» would represent).

When that is done, the evidence for substantial positive feedback from water vapor minus lapse rate, and snow / ice becomes almost inescapable, and the evidence from clouds suggests a positive feedback and excludes a strong negative feedback (long term — see below).

If there is a strong negative feedback in the climate system, be it clouds, lapse rate, etc it would preclude large temperature variations in global temperature caused by a perturbation in climate, regardless of the cause of the perturbation

Elliott et al. conclude, based on the selected data below 500 hPa only that SH (moisture content) increased slightly with warming, but not at a rate sufficiently strong to maintain constant RH, as is assumed by the IPCC models in estimating water vapor feedback.

In AOGCMs, the water vapour feedback constitutes by far the strongest feedback, with a multi-model mean and standard deviation for the MMD at PCMDI of 1.80 ± 0.18 W m — 2 °C — 1, followed by the (negative) lapse rate feedback -LRB--- 0.84 ± 0.26 W m — 2 °C — 1) and the surface albedo feedback (0.26 ± 0.08 W m — 2 °C — 1).

But as Dessler also says, even if the topical troposphere isn't warming faster than the surface, this just means the negative lapse rate feedback isn't as strong, and the sum of WV+LR feedbacks remains the same.
