Long range effects of atmospheric pollution

Long range predictability of atmospheric flows

In the light of recent advances in 2D turbulence, we investigate the long range predictability problem of atmospheric flows. Using 2D Euler equations, we show that the full nonlinearity acting on a large number of degrees of freedom can, paradoxically, improve the predictability of the large scale motion, giving a picture opposite to the one largely popularized by Lorenz: a small local perturba...

Long-range transport modeling of air pollution episodes.

The air quality network in the Netherlands is based on a regular grid with an interstation distance of 30 to 40 km. In or close to source areas, a higher station density is realized. Atmospheric transport models form an intrinsic part of the air quality monitoring system. The models are constructed in such a way that only routinely available meteorological input data are needed. The models are ...

4.2 Acid Deposition Acid rain was first identified in the 19th century, when English pharmacist Robert Angus Smith measured high acidity levels in rain falling over industrial regions of England and much lower levels in less-polluted areas near the coast. However, this pattern did not receive sustained attention until biologists began to notice sharp declines in fish populations in lakes in Nor...

EXECUTIVE BODY FOR THE CONVENTION ON LONG-RANGE TRANSBOUNDARY AIR POLLUTION Working Group on Effects

1. Recent research has shown that there was a significant recovery in water chemistry from 1989 to 1998, following the reduced emissions of sulphur in Northern Europe and North America (Stoddard et al, 1999; Skjelkvåle et al., 2000). This recovery has also been reflected in the macrozoobenthos in some watersheds in southwestern Norway, as documented by the acidification indexes developed at the...
