Abstract: Analysis has been made of seven spring and summer convective showers collected at State College, Pa. The data indicate that the ground-level Sr90 concentration in the precipitation is dependent upon the extent of the ...

Abstract: Analysis has been made of three winter rainstorms, resulting from large-scale uplift, in which the generating level and the precipitation mechanism were essentially constant. The data show that the ground-level Sr90 ...

Abstract: Water droplets in thermal equilibrium with gases of different solubilities were frozen at temperatures between ?4 and ?14C, in order to observe the influence of the volume of dissolved gas on the shattering of the droplet. ...

Abstract: Manipulation of spheres of ice and observations of ice crystals colliding with a fixed crystal under conditions of controlled temperature and vapor pressure have been employed to determine the limiting conditions for the ...

Abstract: The value of climate data and the information derived from the data still seems to be an unknown to many. Five persons engaged in providing climate services in different U.S. climatic zones have assembled a few widely ...
