As part of an international intercomparison project, the weak temperature gradient (WTG) and damped gravity wave (DGW) methods are used to parameterize large-scale dynamics in a set of cloud-resolving models (CRMs) and single column models (SCMs). The WTG or DGW method is implemented using a configuration that couples a model to a reference state defined with profiles obtained from the same mod...

Over the last century, northeast Pacific coastal sea surface temperatures (SSTs) and land-based surface air temperatures (SATs) display multidecadal variations associated with the Pacific Decadal Oscillation, in addition to a warming trend of ∼ 0.5-1 °C. Using independent records of sea-level pressure (SLP), SST, and SAT, this study investigates northeast (NE) Pacific coupled atmosphere-ocean v...

Granular flows are highly dissipative due to frictional resistance and inelasticity in collisions among grains. They known exhibit shock waves at velocities that easily achieved industrial nature-driven such as avalanches landslides. This experimental work investigates the formation of strong on triangular obstacles placed a dry rapid granular stream confined two-dimensional set-up. Oblique att...

The Magellanic Stream is sculpted by its infall through the Milky Way's circumgalactic medium, but rates and directions of mass, momentum, energy exchange Stream-halo interface are relative unknowns critical for determining origin fate Stream. Complementary to large-scale simulations LMC-SMC interactions, we apply new insights derived from idealized, high-resolution "cloud-crushing" radiative t...

Contrary to some recent claims the 'no torque inner boundary condition' as applied at the marginally stable orbit is correct for geometrically thin disks accreting into black holes. A transition from a thin accretion disk to a stream freely falling into a black hole was a topic of many papers about two decades ago. That ancient work is very well reviewed in the introduction of Abramowicz & Kato...

How to determine accurately and efficiently the aerodynamic forces of aircraft in high-speed flow is one great challenges modern aerodynamics. In this Letter we propose a new similarity law for steady transonic-supersonic over thin bodies. The based on local Mach number frozen principle. It depends both specific heat ratio free-stream number. enables lift drag coefficients from that reference s...

Jellyfish outbreaks are increasingly viewed as a deterministic response to escalating levels of environmental degradation and climate extremes. However, a comprehensive understanding of the influence of deterministic drivers and stochastic environmental variations favouring population renewal processes has remained elusive. This study quantifies the deterministic and stochastic components of en...

over the last ten years, robustness of schemes has raised an increasing interest among the cfd community. the objective of this article is to solve the quasi-one-dimensional compressible flow inside a “shubin nozzle” and to investigate bean-warming and flux vector splitting methods for numerical solution of compressible flows. two different conditions have been considered: first, there is a sup...
