Title:Analysis of the diurnal variation of the global electric circuit using different numerical models [poster]
Abstract: Diurnal variation of the global electric circuit (GEC) represents variation of fair weather electric field at ground. It was established by measurements in Carnegie ship in first quarter of the 20th century. The diurnal variation is linked with electrified clouds in our atmosphere and the maximum appears around 19UT when thunderstorms in the Americas are most active.Motivation for this work is to model and compare the diurnal variation of the GEC using several modeling strategies. First, three-dimensional GEC models are employed in connection with climate model. Second, multiple parameterization of fields and currents from overflights above electrified clouds are used to determine global currents with the help of satellite data. It is shown that GEC models based on input from climate models have smaller relative diurnal variation compared to experimental measurements. Models using overflight data are in general giving better agreement with experimental measurements. It is important to mention that a publicly available GEC model is also used here and validated using typical diurnal variation.
