Summary: New-snow density was measured at the Central Sierra Snow Lab., and the air temperature at both 700- and 500-mb levels was used to study the relationship between upper air conditions and the density. The upper air temperatures were determined from radiosonde flights at Oakland (California) immediately prior to or at the same time when the density was measured. A graph of the air temperatures at the 700-mb level against the new-snow density indicates a definite relationship between the 2 variables. The correlation coefficient of 0.639 is significant at the 1 percent level. No relationship was found for the 500-mb level. Surface-air temperatures were plotted against the new-snow density. The correlation coefficient between the variables is 0.503 which is significant at the 1 percent level.
