A Stochastic Representation of the Local Structure of Turbulence

, 2010
Based on the mechanics of the Euler equation at short time, we show that a Recent Fluid Deformation (RFD) closure for the vorticity field, neglecting the early stage of advection of fluid particles, allows to build a 3D incompressible velocity field that

Potential drivers of fast growth in Paulownia

PLANTS, PEOPLE, PLANET, EarlyView.
Trees in the genus Paulownia play a crucial role in sustainable forestry, rural economic development, and carbon mitigation due to their rapid growth, exceptional hardwood properties, and prominent carbon sequestration capacity. This review highlights the societal value of Paulownia trees and synthesizes several potential drivers of extraordinarily ...

STUDY ON METEOROLOGICAL AND TIDAL INFLUENCES UPON GROUND DEFORMATIONS

STUDY ON METEOROLOGICAL AND TIDAL INFLUENCES UPON GROUND DEFORMATIONS
Observational results of the ground deformations obtained by means of tiltmeters and extensometers at two stations in Wakayama City in Kinki District, Japan, are presented and discussed with particular emphasis on the relation to meteorological and oceanic phenomena.

Driving factors analysis and risk prediction of ecological environment in typical coal mining area of Western China

Meitan xuebao
The extraction of coal seam could induce a series of ecological environment problems in arid and semi-arid mining area of Northwest China. In order to clarify the driving factors of ecological environment in coal mining areas and form an ecological risk ...

On the β$$ \beta $$‐effect in the baroclinic instability of a continuously stratified atmosphere

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We solve the quasi‐geostrophic equation numerically to analyze baroclinic instability in a continuously stratified atmosphere. On the β$$ \beta $$‐plane, deviations from classical models alter instability growth rates and modal structures, leading to the emergence of unstable lobes and a stable region at very large wavelengths.

A study of a free convective boundary layer using a parcel‐based Lagrangian model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We study the development of a convective boundary layer forced by surface heating and growing into a stably stratified atmosphere above. We compare our results with several recent comprehensive direct numerical simulation (DNS) studies and find broad agreement, and often close quantitative agreement, despite fundamental differences in the numerical ...

Coriolis force in Geophysics: an elementary introduction and examples [PDF]

, 2000
We show how Geophysics may illustrate and thus improve classical Mechanics lectures concerning the study of Coriolis force effects. We are then interested in atmospheric as well as oceanic phenomena we are familiar with, and are for that reason of ...

When tiny convective spread affects a midlatitude jet: Spread sequence

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate spread evolution by mesoscale convection from tiny initial condition uncertainty during a real event. There is significant variation among the systems in their propensity to interact with the jet stream, whereby variability in one system (due to convective and long‐wave radiative heating tendencies) tightly relates to Rossby‐like ...

Calibration and accuracy assessment of Leica ScanStation C10 terrestrial laser scanner [PDF]

, 2013
Requirement of high accuracy data in surveying applications has made calibration procedure a standard routine for all surveying instruments. This is due to the assumption that all observed data are impaired with errors.
