The classical theory for homogeneous ice nucleation in supercooled water is investigated in the light of recent data published in various physico-chemical journal on the physical properties of supercooled water and in the light of recent evidence that the cooperative nature of the hydrogen bonds between water molecules is responsible for a singularity behavior of pure supercooled water at −45°C. Recent rates for homogeneous ice nucleation in supercooled water drops field from field experiments at the cirrus cloud level and from cloud chamber studies were shown to be quantitatively in agreement with the laboratory-derived lowest temperatures to which ultrapure water drops of a given size have been supercooled. Using these verified nucleation rates together with the recent physical property data for supercooled water, the activation energy for the transfer of water molecules across the ice-water interface was computed using the classical nucleation rate equation. The thus computed values are signif...read more

TL;DR: The behavior of water in the regime from ambient conditions to the deeply supercooled region is described and some of the possible experimental lines of research that are essential to complete a global picture that still needs to be completed.

Aerosol impact on the dynamics and microphysics of deep convective clouds
TL;DR: In this article, a spectral micro-physics two-dimensional cloud model was used to investigate the effect of aerosols on cloud microphysics, dynamics and precipitation, and the results showed that aerosols can contribute to the formation of very intensive convective clouds and thunderstorms accompanied by very high precipitation rates.

Deep convective clouds with sustained supercooled liquid water down to -37.5 °C
TL;DR: In this article, the authors reported in situ measurements in deep convective clouds from an aircraft, showing that most of the condensed water remains liquid down to -37.5°C.
