Sentences with phrase «require warm ocean temperatures»

In order to build up and intensify, hurricanes require warm ocean temperatures, moist air, and low vertical wind shear (i.e. no strong change in wind speed or direction between two different altitudes).

It is still widely believed that tropical cyclone formation requires warm ocean temperatures.

Not exact matches

This interplay between climate and wind can lead to sea level rise simply by moving water from one place in the ocean to another, said Greene — no warming of the air, or of ocean temperatures required.

Second, the quantity of methane necessary to explain the carbon isotope ratio, as calculated by Dickens, would be much less than that required to warm ocean and atmosphere temperatures to the extent estimated by PETM temperature proxies and calculated by physical climate models.

[26] The surface waters of the northernmost [27] Arctic Ocean warmed, seasonally at least, enough to support tropical lifeforms [28] requiring surface temperatures of over 22 °C (72 °F).

The process of evaporation also requires energy from heat, and the warmer the temperatures are in the upper ocean and at the ocean surface, the more energy is available.

To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).

- and MOST IMPORTANTLY, the maths to show how an increase in temperature of the vents (a tiny percentage of the ocean floor), converts to the Joules required to warm the mass of the 700-2000 meter layers of water GLOBALLY.

This figure indicates 3 things: (1) the time lag between emitting greenhouse gases and when we see the principle effect is about 30 years, due mostly to the time required to heat the oceans, (2) the rate of temperature increase predicted by a climate sensitivity of 3 °C tracks well with the observed rate of temperature increase, and (3) we have already locked in more than 1.5 °C warming.

In the Arctic, due to colder - than - average water temperatures, only about 200 m of water depth is required, which increases the vulnerability of those methane hydrates to a warming Arctic Ocean.

Indo - Pacific Warm Pool and what limited ocean heat content data (vertical temperature anomaly) we have to compare the rate of warming required for full recovery from the LIA.

The current warming trend can not be due to «natural variability» because at present both ocean temperatures and land temperatures are warming which requires an external forcing and land temperatures are warming faster than ocean temperatures which can not occur with internal variability of the ocean - atmospheric system.
