o–Southern Oscillation (ENSO) and the Northern Hemisphere wintertime stratospheric polar vortex appears robust in observational studies focusing on the period before 1979 and in many modeling studies, this connection is not evident over the past few decades. In this study, the factors that have ...
If communications fail, the danger exists for one class of professional to dismiss the efforts of the other as either irrelevant or hopelessly unsophisticated. Whose problem is it? 11.4 Jumping Zoonoses: The Problems of Long-Distance Translocation National and international long-range translocations of...
That is to say, a nonstandard order of infinity is an equivalence class of functions defined on elements of the ultrafliter. For instance, if is the natural numbers, then itself is an order of infinity, as is , , , , and so forth. But we exclude ; it will be important for us ...
MRI is also able to quantify water diffusion within tissues. Strong field gradients applied on each side of a 180° refocusing pulse cause diffusion-mediated signal attenuation due to phase dispersion of spins. Conversely, in static tissue, the effect of both gradients cancels out and the signal ...
Much of Dartmoor is a SAC, with boundaries that coincide with existing six SSSIs. Of particular interest are: Blanket bog Northern Atlantic wet heath Dry heath Old sessile oakwoods Southern damselfly Otter Atlantic salmon Of these, salmon are the key feature of the Dartmoor SAC. ...
El Nino-Southern Oscillation (ENSO) cycles can have considerable impacts on this phenomenon. Indeed, ENSO is largely responsible for the high degree of inter-annual variation in Arizona precipitation [17]. El Nino phases typically increase low-intensity winter precipitation, and can also cause winter...
Here’s a look at what these weather events are, why they happen, and whether scientists think they’re getting stronger.
it can shift a little north or south in its position. A good example of a switching pressure-pattern occurs in the Arctic and is known as the Arctic Oscillation (AO). When atmospheric pressure over the Arctic is low and pressure over the mid-latitudes is high, theAOis said to be in ...

Changes in large-scale circulation, especially El Nio–Southern Oscillation (ENSO), have significant impacts on dust activities over the dust source and downwind regions. However, these impacts present an interdecadal pattern, and it remains less clear which factors lead to the ...
