Physics of Atmosphere Dynamic or Electric Balance Processes Such As Thunderclouds and Related Lightning Flashes

Clausius-Clapeyrons’ formulas show precisely that, unlike dry water vapor that can be assimilated to the ideal gas at all circumstances, saturated water vapor has, in an air parcel at the same time very cold (temperatures below 0.0098℃) and rich in moisture (vapor pressure above 6.11 mb), thermoelastic properties diametrically opposed to those of ideal gas (including dry water vapor). Given the fact that saturated water vapor is known as the birthplace of meteorological events such as thunderclouds and electrical processes related, we want to make a contribution to a better understanding of lightning flashes triggered by major tropical disturbances such as cyclones or hurricanes. Taking into account the vertical profiles of temperature and water vapor in the troposphere leads to localization of the region in which the ideal gas assumption should be banned, hence the appropriate repartition of electrical charges within thunderclouds and the better understanding of related lightning flashes.
