The paper explains that diminished specific gravity, differential horizontal motion, and sun's heat expansion contribute to the formation of various cloud forms, including cumulus, stratus, and cirro-cumulus.

On the Forms of Clouds

Recent research reveals that artificial stimulation of clouds may be possible, with a new theory on ice crystal formation and potential for rain formation in tropical clouds.

The microphysics of clouds

Cloud forms and names are crucial for weather forecasting, and this paper provides a brief overview of the subject for those who have not studied it in detail.

The Forms of Clouds

The giant molecular filament GMF38.1-32.4a shows two different evolutionary stages, with the eastern subregion forming a molecular cloud out of atomic gas and the western subregion showing high column density peaks and active star formation.

Cloud formation in the atomic and molecular phase: H I self absorption (HISA) towards a giant molecular filament

Cooling mechanisms can be either natural or artificial, and can be influenced by factors such as aerosol abundance, temperature, and pressure gradients.

Physics and Chemistry of Clouds: Cloud formation and evolution

Turbulent fluctuations in relative humidity play a crucial role in cloud formation, transforming the traditional view of cloud formation into a fluctuation-dominated regime.

The role of turbulent fluctuations in aerosol activation and cloud formation

This study developed a general approach to cloud formation, considering heat and water-vapor flow equations in a turbulent atmosphere, to better understand the formation and development of various cloud types in nature.

Dynamic factors in the formation of the earth’s cloud field

Current estimates of indirect aerosol forcing may be too low, as current insights into cloud formation suggest that current estimates may be too low.

Reshaping the Theory of Cloud Formation

This study demonstrates the turbulent nature of convection and gradual growth of cumulus clouds in an experimental setup, aiding in cloud formation prediction for known environmental conditions.

Experimental Study of Cloud Formation

Solar variability may influence cloud formation through ionization and changes to cloud condensation nuclei and ice nuclei, but definitive experimental work is needed for confirmation.

Cloud Formation and the Possible Significance of Charge for Atmospheric Condensation and Ice Nuclei

Small cloud droplets grow into drizzle drops through collision and coalescence, with collision and coalescence being the most important growth mechanism in warm clouds.

Theoretical Collision Efficiencies for Small Cloud Droplets in Stokes Flow

Molecular clouds may form not by in situ cooling of atomic gas, but rather by the agglomeration of the dense phase of the interstellar medium, much of which is already in molecular form.

The formation of molecular clouds

This publication provides useful information for meteorological observers, but some of the photographs are not quite typical and some are not clear.

Cloud Forms

Near atmospheric concentrations of secondary organic aerosol (SOA) are necessary for accurate predictions of their cloud-forming potential, with supersaturation decreasing with age.

Cloud forming potential of secondary organic aerosol under near atmospheric conditions

Satellite-based analyses reveal distinct microphysical processes in continental and maritime convective clouds, with glaciation occurring at 20°C or higher in highly continental clouds.

Satellite-Based Insights into Precipitation Formation Processes in Continental and Maritime Convective Clouds

SubLCL clouds form on cloud-free days due to humidified parcels in mid-boundary layer, with the height of the lifting condensation level and relative humidity near the BL top being good predictors.

The Environmental Conditions Behind the Formation of Small (subLCL) Clouds

Aerosol concentrations in the atmosphere significantly influence the thermodynamic properties of warm convective cloud fields, with polluted conditions suppressing rain formation and destabilizing the layer, while clean conditions precipitate and stabilize the atmosphere.

Aerosol effect on the evolution of the thermodynamic properties of warm convective cloud fields

Thermal instability is unlikely to be a viable mechanism for cold cloud formation around disc galaxies, as it requires a nearly flat entropy profile and low-mass systems.

Do high-velocity clouds form by thermal instability?

Cirro-filum, or ice-cloud disposed in threads, is a remarkable cloud formation, and its formation is well-researched in papers by Linn and myself.

A Remarkable Form of Cloud

These studies suggest that clouds form due to factors like diminished specific gravity, differential horizontal motion, sun's heat expansion, turbulent fluctuations in relative humidity, and cooling mechanisms influenced by aerosols, temperature, and pressure gradients.
