Sentences with phrase «shifting air currents»

The fly must home in on the fruit by tracking the odor, it must navigate the complex visual flow of a three - dimensional world and, all the while, it must maintain flight speed and direction in the face of shifting air currents.

Not exact matches

Current projects focus on air pollution, occupational exposures such as shift work, biomarkers such as melatonin, vitamin D, and sex hormones, and other factors such as physical activity, and genetic variants.

Warming air temperatures, melting ice, and shifting currents are totally altering the ocean ecosystem, affecting the people, plants, and animals that call it home.

The fish move with the gallery's air currents, visitors enter and exit, and natural light from adjacent windows shifts continually according to the weather and time of day.

Real scientists (as opposed to climate modellers) have long maintained that the decline in Arctic ice is caused not by warmer air — in the past year or two Arctic air temperatures have actually been falling — but by shifts in major ocean currents, pushing warmer water up into the Arctic Circle.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

Yes, the simple term «global warming» doesn't convey all the complexities of what can happen as that warming causes air and ocean currents to shift, but climate change / disruption provides even less information.

When the low shifts as far south as Newfoundland, a high develops over northern Greenland; this brings cold arctic air west from northern Europe to be warmed by the Norwegian Current and thus warm Greenland and North America rather than Europe.

George Tselioudis, a climate scientist at NASA's Goddard Institute for Space Studies and Columbia University in New York City, was interested in which air currents were shifting clouds at high altitude — between about three and a half and six miles high — toward the poles.

The previous suggested reason was that climate change was shifting storms and the powerful air currents known as the jet streams — including the one that traverses the United States — toward the poles, which in turn were driving the movement of the clouds.

Also, it may be that a change in the air currents caused by global warming represents a fundamental yet poorly understood shift in climate patterns.

The steering of Hurricane Sandy into the New York and New Jersey metro areas, the extreme killer cold in Eastern Europe and Russia, the «year without a Spring» and the very mild winters, dome of the features of drought, and other effects may be «the new normal» owing to a basic shift in how air currents are set up in a high - CO2 world.

Shifts in clouds, water vapor, and the great currents in the ocean and air, however, cause complex responses in which some regions warm more than the average while others warm less than average, or even cool.

What appears to happen is the upper air currents shift from more zonal flows to more cross zonal flows as evidenced in the N. Jet Stream.
