Changes in high-altitude winds over the South Pacific produce long-term effects

In the past million years, the high-altitude winds of the southern westerly wind belt, which spans nearly half the globe, didn't behave as uniformly over the Southern Pacific as previously assumed.

A new study has now confirmed close ties between the climate of the mid and high latitudes and that of the tropics in the South Pacific.

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.

Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.

Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
