Alternative title(s)

d820000

Abstract

<p>Winter seasonal circulation statistics for the Northern Hemisphere were derived from NMC analyses by Ngar-Cheung (Gabriel) Lau. Grids are available at various tropospheric levels between 1000 and 100 millibars. The period of record is 1965 to 1976, with each winter consisting of the 120 days beginning November 15.</p>
