1968 FLORIDA CUMULUS SEEDING EXPERIMENT: NUMERICAL MODEL RESULTS

Cloud Seeding Experiment

The experimental data are the result of a series of weather modification experiments conducted in south Florida from 1968 to 1972. These experiments were designed to test a hypothesis that massive injection of silver iodide into cumulus clouds can, under specified conditions, lead to cumulus growth, thereby increased precipitation. On each of 52 days that were deemed suitable for cloud seeding,...

A Numerical Model to Investigate Optimum Liquid Carbon Dioxide Seeding Rate in Weather Modification Projects

A numerical model of the VKS experiment

We present numerical simulations of the magnetic field generated by the flow of liquid sodium driven by two counter-rotating impellers (VKS experiment). Using a kinematic code in cylindrical geometry, it is shown that different magnetic modes can be generated depending on the flow configuration. While the time averaged axisymmetric mean flow generates an equatorial dipole, our simulations show ...

Quantum gate identification: error analysis, numerical results and optical experiment

The identification of an unknown quantum gate is a significant issue in quantum technology. In this paper, we propose a quantum gate identification method within the framework of quantum process tomography. In this method, a series of pure states are inputted to the gate and then a fast state tomography on the output states is performed and the data are used to reconstruct the quantum gate. Our...
