Sentences with phrase «warm background temperature»

In the case of Scottsbluff, Vatistas and his team found that the temperature inside the tornado would have dropped from a comfortably warm background temperature of 27o C to a chilly 12o C. And at the tornado's centre, the researchers estimated the air density would have been 20 per cent lower than what's found at high altitudes.

Not exact matches

Background When water is warm or even room temperature, its molecules are moving around, bumping into one another.

But the CMB was hotter earlier on in the universe — Avi Loeb of Harvard University has previously pointed out the universe's background temperature would be 300 kelvin (27 ˚C) around 15 million years after the big bang, making it warm enough to host liquid water.

While weather and natural climate patterns play a role in temperatures across the U.S., the overall background warming of the planet has tipped the odds in favor of heat records and away from cold ones.

It is this background warming from the heat trapped by greenhouse gases that actually accounts for most of the predictability in future temperature change, said Michael Mann, a climate scientist at Penn State.

The point at which a trend becomes clear within the average temperature data for a given region — known as the «time of emergence» — depends on when the source of the warming begins, how fast it happens and the amount of background «noise» obscuring the signal.

Global warming has also raised background temperatures, making record - setting heat more common.

point triumphantly to the cosmic microwave background temperature of the last century and declarethat warming impossible on the grounds that it's only 4.6 Kelvin in all directions as far as you can look.

Or are they missing natural influences that can cause wide swings in ice and temperature, thereby dwarfing the slow background warming?

The research that shows that decade - long periods of static / declining temperatures are to be expected against the background of a warming trend (see the Spiked article above) makes no claims that such natural variation could account for the much longer post-war slump.

In theory, any warming should be proportional to the fourth root of (wattage new / wattage old) and the wattage change should be proportional to the logaritm of the change in CO2 - that would give small temperature changes quite difficult to measure through the background noise.

My opinion expressed elsewhere is that almost all the temperature changes we observe over periods of less than a century are caused by cyclical changes in the rate of energy emission from the oceans with the solar effect only providing a slow background trend of warming or cooling for several centuries at a time.

We conclude that background global warming is continuing, consistent with the known planetary energy imbalance, even though it is likely that the slowdown in climate forcing growth rate contributed to the recent apparent standstill in global temperature.

«Barring a large volcanic eruption, a record global temperature clearly exceeding that of 2005 can be expected within the next few years, at the time of the next El Nino, because of the background warming trend attributable to continuing increases of greenhouse gases.»

I would probably generally state it as «human CO2 activity has a measurable warming impact on global average temperature that can be readily discerned from the background of natural climate change and other human effects that may cause cooling, and this warming impact will be, in general, neutral in impact for humanity and the biosphere».

Jeff Masters, a meteorologist with a bent to blaming every weather event on global warming, chose to make some extreme claims about hot ocean temperatures that are... er... well, bizarre for someone with a science background.

They actually say something different:» For example, most mid-latitude studies show that the heat island intensity (the difference between the temperature of the warmest location in the city and the background rural value) of the near surface air layer reaches its maximum a few hours after sunset on calm.

I extend the suggestion to you regarding writing an article on the background to «the warmest year ever» in which the temperature records of the 17 countries who are experiencing their hottest year ever needs to be objectively examined and put into the context of the 183 who aren't.

Scientific Background Global warming refers to the phenomenon of increasing average surface temperatures of the Earth over the past one to two centuries.

Hence the temperature trends over the past 135 years can be synthetized the superposition of a background linear warming trend with a triangular shape fluctuation, whose slope is +0.06 + / - 0.11 °C per decade.

With the ever increasing divergence of surface temperatures (NASA GISS) from satellite ones (UAH / RSS), and the subsequent divergence of overheated climate models (IPCC CMIP5) to observed reality, it is worth some background on the atmospheric temperature measurement systems used to measure the temperature of the lower troposphere — the exact place where global warming theory is meant to occur and be measured:

First, we note that the record can be divided into three eras, consisting two perturbed climates — the rapid warming after the end of LIA and the modern period of anthropogenic warming after the Second Industrial Revolution — separated by a background climate when Europe experienced a century (1738 — 1849) of mild temperature with no trend.

Steve Reynolds (29)-- I'm an amateur with enough background, by now, to compare some of the «regional hydrology» predictions with paleoclimate at times with warm regional temperatures.

He was right about so many things — the background nineteenth - century CO2 concentration level and its increase over the twentieth century; the importance of high - quality temperature data and the warming trend observed over much of his lifetime; the infrared spectroscopy of CO2 and its effect on «sky radiation»; and more.

When a PIR sensor detects sufficient movement of these warm «objects» and / or a significant temperature differential between the object and the background scene, it signals the camera to start recording and send an alert to the user.

This device surprisingly doesn't get warm while charging and keeps the temperature at cool 30C and doesn't heat up with multiple apps in the background.
