14. From (4, 5) we obtained the following: The enhancement factor for dust particles (radius > 0 4 μm) at dome C in Antarctica is 9 to 14; the enhancement factors for the elements Al, Na, and Cl are 34, 4 9, and 3.8, respectively; and the enhancement factor for dust particles in Greenland is 100.

17. There is no ice core data for low latitudes at sea level. However, ice cores taken from mountain glaciers show that dust contents are enhanced in the LGM layer [L. G Thompson et al., Science 246, 474 (1989); L G. Thompson et al , ibid. 269, 46 (1995)]. It is difficult to interpret the dust deposition rates in the high mountains because of possible changes in local meteorology during the LGM. The beauty of the polar data is that the poles are remote regions of the globe and any enhancement must be related to changes on a global scale (global change)

25. The 2D model has four components: the photochemical module, the solar-radiative module, the infrared-radiative module, and the transport module. The model has 18 latitudes, from pole to pole There are 40 layers, from 0 to 80 km in log pressure coodinates. Time-stepping is 1 to 4 steps per day. We usually used model times of 10 to 20 years to obtain convergence. The monthly averaged transport coefficients were computed by the method of H Yang et al. [J Atmos. Sci 48, 442 (1991)]. The details are described in R. L. Shia et al [J. Geophys. Res. 94, 18467 (1989)]. We adopted in the 2D model washout lifetimes computed with a 3D model by Y J. Balkanski et al [ibid. 98, 20573 (1993)].

34. The saturated vapor pressure of water decreases by 34% from 30° to 25°C; thus, a change of 5°C in SST alone is not sufficient to cause a difference of a factor of 2 in the water vapor content of the atmosphere.
35. L D D Harvey, Nature 334, 333 (1988). We wish to speculate on the effect of atmospheric dust on the tropical "warm pool." Today a major source of moisture is the warm pool (with SSTs often >29°C) in the tropical western Pacific Ocean around Indonesia and New Guinea. If the combination of a lower ocean level (by 150 m), stronger winds, and atmospheric dust opacity were to reduce the SST of the warm pool by 10°C, this would decrease the source of moisture by half The reduced moisture would greatly reduce the greenhouse effect caused by water vapor, thereby contributing to the cooling of the tropics.
