Sentences with phrase «warmer air temperatures far»

From the Southwest to the Great Lakes, temperatures have been so high and rainfall so low that the drying effect of warmer air temperatures far exceeded what little precipitation there's been, resulting in moisture being drawn out of soils.

Not exact matches

«Warm temperatures in the Arctic cause the jet stream to take these wild swings, and when it swings farther south, that causes cold air to reach farther south.

The temperature differential between the cold of the far North and the warmer air of the temperate zones to the south fuel the jet stream, which steers weather patterns in the Northern Hemisphere.

September is by far my favorite month with the crisp morning air that turns into warm summer - like temperatures by day's end, the abundance of pumpkin spiced everything (although I can't get on board with the overly sweet Starbucks #PSL), and an excuse to finally don a sweater.

If a larger mass of warm air has to pass through it, more energy is transferred, through the evaporator's fins (so that even the evaporator's design and, in particular, its exchange surface play an important part) from the air to the liquid refrigerant allowed inside it by the TEV or orifice tube so it expands more and, along with the absolute pressure inside the evaporator, the refrigerant's vapor superheat (the delta between the boiling point of the fluid at a certain absolute pressure and the temperature of the vapour) increases, since after expanding into saturated vapour, it has enough time to catch enough heat to warm up further by vaporizing the remaining liquid (an important property of a superheated vapour is that no fluid in the liquid state is carried around by the vapour, unlike with saturated vapour).

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).

What is unusual is the amount of melting so far in the Antarctic, spurred by warm air temperatures and shifting winds.

«The dramatic changes in lake ice may also contribute to further warming of the entire region, because open water on lakes contributes to warmer air temperatures, albeit to a lesser extent than open seawater,» Surdu said.

Satellite pictures (below) clearly show that the recent loss of winter Arctic ice has occurred along the pathway by which warmer waters enter the Barents Sea, deep inside the Arctic Circle, while simultaneously air temperatures far to the south remain cold enough to maintain a frozen Hudson Bay.

The conditions for both the warmest and driest years is generally created, the scientists said, when increased coastal temperatures warm air in the lower atmosphere, creating a ridge of high pressure that ramps up temperatures even further and blocks rain - bearing storms from reaching the state.

As the CO2 and CH4 (methane) level goes up, H2O vapour in the atmosphere falls which — because H2O is 30 times more important than CO2 as a «greenhouse gas» offsets the effect of CO2 on temperature, while cloud cover and albedo increases because warmed moist air rises to form clouds, further cooling the world.

According to the National Oceanic and Atmospheric Administration, NASA, the UK Met Office, and other groups that monitor the planet's thermostat, 2017 was by far the warmest year to occur without an El Niño event, which can boost ocean and air temperatures and was partly responsible for propelling 2016 to the top spot on the list of warmest years.

Depending on how far east winter storm tracks travel up the east coast, the battle line between cold arctic air masses to the west and warm Atlantic air to the east causes significant temperature changes.

«In Antarctica's far north (Anvers Island) air temperatures have become VERY warm and ice no longer forms on the sea.»

All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.

The «Beast from the East» was the name given by the media to an unusual weather pattern which saw warmer that average temperatures over the arctic sending colder air further south than normal, resulting in much of western Europe being hit with sustained low temperatures and heavy snow, blown in from Siberia.

TIS, There's a huge difference between the air temperature in the few meters near the surface, which is warmed by conduction and radiation off the immediate surface and the rest of the troposphere, which is warmed by influences from far away.

Craig King - Further to Bob Loblaw's comments; that global surface air temperatures are warming faster than upper ocean temperatures is well - observed and completely uncontroversial.

Stroeve and her colleagues are also starting to see evidence of Arctic amplification — the phenomenon by which the lower amount of ice in the summer leads the ocean to absorb more heat, which is then released in the autumn as air temperatures drop, bringing further warming.
