Southern Hemisphere Atmospheric Circulation Effects of the 1991 Mount Pinatubo Eruption
1 Global average cooling and Northern Hemisphere winter warming are well-known 2 climatic responses to the June 15, 1991 eruption of the Mount Pinatubo volcano in the 3 Philippines. Here we investigate the Southern Hemisphere response. Using National Centers for 4 Environmental Prediction/National Center for Atmospheric Research Reanalysis, European 5 Centre for Medium-Range Weather Forecasting...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولFinal warming of the Southern Hemisphere polar
6 The final warming date of the polar vortex is a key component of 7 Southern Hemisphere stratospheric and tropospheric variability in spring 8 and summer. We examine the effect of external forcings on Southern 9 Hemisphere final warming date, and the sensitivity of any projected changes 10 to model representation of the stratosphere. Final warming date is cal11 culated using a temperature-base...
