Book Description
The purpose of this monograph is to present an analysis of all the factors that determine the susceptibility of a radar altimeter to a false indication of height because of rain clouds. This analysis will be precise enough and general enough to determine whether any altimeter is safe from this effect. If this check should reveal a doubtful condition, the analysis shows how much the transmitter frequency should be decreased.

Book Description
This soothing book is the perfect invitation to a relaxed afternoon of cloud gazing. It starts by encouraging young readers to observe what clouds look like, from thin wisps to puffy air castles to giant faces. Then the story raises natural questions: Where do clouds get water? Why does it rain? When rain makes puddles and puddles dry up, what happens to the water? The answers give children an easy-to-grasp picture of the water cycle while instilling the kind of curiosity that can lead to a lifetime of experiencing the world from a scientific perspective. Clouds, Rain, Clouds Again is part of the I Wonder Why book series, written to ignite the curiosity of children in grades K–6 while encouraging them to become avid readers. These books explore the marvels of geology, land forms, weather, environments, and other phenomena related to science and nature. Included in each volume is a Parent/Teacher Handbook with coordinating activities. The I Wonder Why series is written by an award-winning science educator and published by NSTA Kids, a division of NSTA Press.

Book Description
The problem of electrical charges on raindrops from non-thunderstorm clouds is investigated. Measurements of raindrop charges, precipitation currents and space charges made in various parts of the world indicate that on the average positive charges prevail on raindrops. To explain rain charges, a well known hypothesis requires the melting of snow. In Hawaii, however, rain often forms by condensation and coalescence without ice or snow in the upper portions of the cloud. Yet raindrop charges do not differ from charges measured in other types of rain. Measurements of charges on Hawaiian rain are discussed together with observations of electrical field and condensation nuclei profiles. It was found that positive charges are of the order of 10−4 esu. A correlation of these charges with wind speed was found. Electric fields in rain clouds are generally positive except at the lower cloud boundary where negative fields of up to -1000 V/m exist. Several thunderstorm theories are discussed and their applicability to the warm mechanism is examined. A new hypothesis is necessary to explain the observed electrical features of warm rain. A theory based on influence is presented and formulated. Due to low electrical conductivity inside the cloud, positive space charges form in the upper part of the cloud and negative in the lower, influenced by an impressed conduction current from above the cloud. These space charges diffuse to the raindrops. Considering a coalescence mechanism for drop growth, the residence time of raindrops in the negative space charge area is much smaller than the corresponding time in the positive area, and so the drops usually leave the cloud with a positive charge. Numerical solutions to drop charges and electric field profiles using a realistic cloud model were obtained through the use of digital computer techniques. The theoretical results for charges on raindrops and electric field patterns agree well with observations.
