Small, solid‐propellant rockets carrying meteorological instruments to altitudes beyond the capability of conventional balloons have provided a relatively large number of direct measurements of wind and temperature in the mesosphere. Data are presented from 110 meteorological‐rocket launches made at Point Mugu, California, during a 17‐month period. They show (a) strong reversal in the mesospheric zonal flow from winter to summer; (b) temporary breakdown in the winter westerlies in late January; (c) reversal in the meridional flow between 40,000 and 70,000 feet from winter to summer; (d) at least three meridional circulation cells in the vertical; (e) large temperature fluctuations in the mesosphere but good correlation, in the mean, with the ARDC Model Atmosphere.
Stamp collecting is one of the most popular hobbies in the world. Started shortly after the first adhesive postage stamp, the Penny Black, was issued by the British on May 6, 1840, the hobby is well over a century old. Many well-known dignitaries, including King George V of England and Franklin D. Roosevelt, did much to popularize stamp collecting which has become known as the "hobby of kings and the king of hobbies." Stamps, the world over, are printed in exquisite designs and colors and on a multitude of topics. The hobbyist has a wide choice for specializing in different topical areas. Stamps portraying animal life, sports events, aviation, famous paintings and historical persons are but a few of the areas in which he may become interested. In line with our profession, the topical area of meteorology and atmospheric physics is explored.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
