Atmospheric Electricity and Cloud Microphysics
The terrestrial atmospheric electrical system covers a range of dimensional scales, from charged molecular clusters to convective cloud systems. Charge-exchange associated with thunderclouds leads to positive charge in the upper conductive regions of the atmosphere and a net negative charge on the planetary surface. In non-thunderstorm regions, a vertical ionic current flows, replenishing the a...
متن کاملGlobal Electric Circuit and Lower Atmospheric Electricity
This short report describes some recent results of global electric circuit investigations. The experimental foundation of global electric circuit conception is discussed. The main origins of global electric circuit formation are examined. The electrodynamical properties of fair-weather electricity are characterized with standpoint of universal spectra and aeroelectrical structure availability. ...
متن کاملAtmospheric nitrogen evolution on Earth and Venus
Nitrogen is the most common element in Earth’s atmosphere and also appears to be present in significant amounts in the mantle. However, its long-term cycling between these two reservoirs remains poorly understood. Here a range of biotic and abiotic mechanisms are evaluated that could have caused nitrogen exchange between Earth’s surface and interior over time. In the Archean, biological nitroge...
متن کاملDepartment of Earth and Atmospheric Sciences
We first review some history of the Global Geodynamics Project (GGP), particularly in the progress of ground-satellite gravity comparisons. The GGP Satellite Project has involved the measurement of ground-based superconducting gravimeters (SGs) in Europe for several years and we make quantitative comparisons with the latest satellite GRACE data and hydrological models. The primary goal is to re...
متن کاملOEAS - Ocean, Earth and Atmospheric Sciences
OEAS 108N. Understanding Global Climate Change. 4 Credits. What is the science behind global climate change? How reliable are forecasts of future global warming? This course examines these questions to evaluate the likelihood and potential severity of anthropogenic climate change in the coming centuries. It includes an overview of the physics of the greenhouse effect, an overview of the global ...
