The COVID-19 pandemic has illuminated the lack of knowledge regarding the airborne
transmission pathway of disease. The pathway consists of pathogens contained in small …

Collisional growth of droplets, such as occurring in warm clouds, is known to be significantly
enhanced by turbulence. Whether particles collide depends on their flow history, in …

Clouds are crucial to the Earth's radiation budget and energy balance. Inadequately
resolved cloud processes are a major source of uncertainty in weather forecasts and climate …

Particle tracking in turbulent flows is fundamental to the study of the transport of tracers,
inertial particles or even active objects in space and time, ie the Lagrangian frame of …

We present an experimental study on the motion of a spherical droplet in a plane traveling
sound wave. The experiments were performed in the test section of a tunnel with two …

It is a long-standing problem to find the mechanisms how the onset of rain occurs as rapidly
as observed in warm clouds. In the so-called size gap, where neither condensation nor …

Low-level mixed-phase clouds (LLMPCs) shroud large portions of Earth's surface at high
latitudes. They have been shown to dramatically affect the surface energy budget, yet, large …

Deficiency in understanding some key cloud-related processes is the major source of
uncertainty in weather prediction, climate science, and atmospheric circulation modeling …

Clouds consist of water droplets and ice particles that are dispersed within a highly non-
stationary, inhomogeneous, and intermittent turbulent flow (Bodenschatz et al. 2010). Earth's …

Aerosol-cloud interactions are a primary source of uncertainty in the global properties of
clouds and their response to human influences. Aerosol particles become cloud droplets, or …
