This study developed a volume scan-type disdrometer and investigated the size distribution of solid-precipitation particles observed by flux- volume-scan type disdrometers, installed in 2016-2017 winter Sapporo, Japan. The former detected particles, line sensors, which frequency is proportional to particle number per area. On other hand, latter directly using an image sensor. flux-scan data are...

[1] The temporal and spatial variability of vertical salt flux in the Fraser River Estuary, British Columbia, was investigated observationally, using several different direct and indirect indicators of buoyancy flux. Data were collected from the estuary using shipboard instrumentation, primarily an acoustic Doppler current profiler and a towed conductivitytemperature-depth unit. Direct estimate...

The net ecosystem metabolism of the seagrass Thalassia testudinum was studied across a nutrient and productivity gradient in Florida Bay, Florida, using the Eulerian control volume, eddy covariance, and biomass addition techniques. In situ oxygen fluxes were determined by a triangular Eulerian control volume with sides 250 m long and by eddy covariance instrumentation at its center. The biomass...

A T-S volumetric census, with a resolution of 0.2°C and 0.1 psu, for years 20-25 of the World Ocean Circulation Experiment Community Modeling Effort eddy-resolving simulation of the equatorial and North Atlantic Ocean, reveals how the thermohalipe character of the model has changed from the initial conditions, which were taken from the Levitus climatology. Any changes in the thermohaline struct...

Volume integral formulations for solving electromagnetic problems in the frequency domain are proposed. Firstly, it is based on a magnetic flux B and current density J facet interpolation for representing the electromagnetic problem through an equivalent circuit. Secondly, magnetic vector potentials A and electric vector potential T are considered thanks to discrete geometric approach. The form...

We study here the discretization by monotone finite volume schemes of multi-dimensional nonlinear scalar conservation laws forced by a multiplicative noise with a time and space dependent flux-function and a given initial data in L(R). After establishing the well-posedness theory for solutions of such kind of stochastic problems, we prove under a stability condition on the time step the converg...

An adaptive ADER finite volume method on unstructured meshes is proposed. The method combines high order polyharmonic spline WENO reconstruction with high order flux evaluation. Polyharmonic splines are utilised in the recovery step of the finite volume method yielding a WENO reconstruction that is stable, flexible and optimal in the associated Sobolev (BeppoLevi) space. The flux evaluation is ...

[1] We have developed a thermal model of Titan’s interior to study changes in volume during partial freezing or melting of a subsurface ocean due to heat flux variations from the interior. We find that the long‐term cooling of Titan can cause global volume contraction DV/V ∼0.01. We then simulate two‐dimensional contractional deformation of Titan’s icy lithosphere, finding that contractional de...

Abstract. We introduce a new computational technique for evolving interfaces, the flux-based level set method. A nonlinear degenerate advection-diffusion level set equation is discretized by a finite volume method using a complementary volume strategy. It enables to solve the problem in an efficient and stable way. Using a flux-based method of characteristics for the advective part and a semi-i...
