Smoke in the Atmosphere Inhibits Rainfall "So knowing how airliners and rockets add to the picture is important for climate research," she said. For the first time, researchers have proven that In the end, Thompson said, the findings showed that smoke from forest fires inhibits rainfall.

In these clouds, scientists found, the United States Ratifies the Convention of th e Worl d Meteorological Organization The President on May 4, 1949, ratified the Convention of the World Me- teorological Organization opened for signature at Washington on October 11, 1947, and a related protocol concerning Spain opened for signature at the same time. Advice and consent to ratification of the convention and related proto- col was given by the Senate on April 20,1949 . The United States instrument of ratification was deposited on May 4, 1949, in the archives of the Govern- ment, which is designated by the Convention as the depositary government. [ . . . ] Upon its entry into force the Convention will establish the World Meteorological Organization, the basic objective of which is to coordinate, standardize, and improve world meteorological activities and to encourage an efficient exchange of meteoro- logical information between countries in the aid of human activities. [ . . . ] As soon as the World Meteorological Organization comes into being, it will take place as one of the specialized agencies of the United Nations along with aviation, telecom- munications, and postal organizations dealing with problems of transport and communica- tions.
