The ice-forming ability of silver-iodide smoke depends upon the size of the smoke particles in a way which can be calculated. From this relation, it is possible to find the maximum number of nuclei produced, per gram of ...

Analysis of the histories of spiral rain bands as observed on radar indicates that they are usually formed near the center of the storm and propagate radially outward. The rain band, therefore, maintains a quasi-conservative ...

Measurements have been made of the radii and free electric charges of cloud particles in supercooled cumuliform-type clouds which occurred at a 6580-ft MSL mountain observatory. Simultaneously, the positive and negative ...

It was observed that antennae were electrified during heavy snowfalls and that their potential reached several thousand volts at Mt. Teine. The electrification of the antennae was also observed during rainfalls at Sapporo. ...

Hodographs of resultant surface winds are presented for each hour of the day for July and August at stations in the Columbia Basin of eastern Washington and Oregon. Marked diurnal wind variations occur at all stations, and ...

From about five years (1952 to 1956) of radiosonde data over the United States, taken by fifteen radiosonde stations that had been conducting four observations a day, the mean temperatures at the four observational hours ...

Advection of dry air aloft ahead of the upper-level trough forms a convectively unstable layer which transforms a relatively uniform echo to a cellular pattern with echo top at a lower elevation. A characteristic sequence ...

More than 1000 hr of radar records taken with the APS-34 1.25-cm vertical-beam radar during a four-year period have been readily classified into four clearly recognizable types. A limited number of precipitation growth ...
