Tropical cyclone momentum and energy fluxes
… to determine angular momentum and enthalpy fluxes at the sea surface. These results show that the intensification of a hurricane is very sensitive to the values of the coefficients defined in these formulae (Emanuel, 1995). Using these formulae allows the model to make bulk estimates of …

Estimating Soil Moisture and Energy Fluxes Using Assimilation of Remotely Sensed Land Surface State Variables
… in the land surface models predicting these fluxes, better predictions can be obtained by assimilating hydrologically relevant remotely sensed data into the predictive models. We consider two approaches. In the first approach, we update the soil moisture profile and thus the associated energy …

Investigation of covariability between energy fluxes and CO2 exchange over a semi-arid savanna (Kruger National Park) by Eddie Covariance Technique
… lies in studying the connection between energy flows and Net Ecosystem Exchange (NEE) at the semi-arid savanna of Kruger National Park to gain a more detailed and accurate understanding of these processes, especially in semi-arid savannas that are susceptible to changes in environmental …

Understanding scale impacts of heterogeneity and topography on water and energy fluxes in mountain meadows using a fully-integrated hydrologic model
… rates, subsurface flow, soil moisture, and energy flux distributions. Many hydrologic models operate at scales which do not capture the variability of these parameters, often because of limited availability of computational resources and high-resolution data. The effects of these small-scale …

Analysis of the spatial heterogeneity of land surface parameters and energy flux densities
… heterogeneity of land surface parameters and energy flux densities obtained from both satellite observations with different spatial and temporal resolutions and in-situ measurements. The investigations were carried out for two target areas in Germany. First, satellite data for the years 2002 …

Currents through the Golden Gate
… dimensional structure of the Golden Gate. Mean energy fluxes at the site were 30,000 W for kinetic energy advection and 8,500,000 W for the work done by pressure. If representative of the channel, they imply a total energy flux of 8. 5 x 1O to the 9th power W through the Gate

Generation and propagation of longitudinal tube waves in late-type stellar atmospheres and the rotation-emission activity relation
Generated longitudinal tube wave (LTW) energy fluxes as a result of the interaction of magnetic flux tubes with the turbulent medium of the convection zones of late-type stars were computed. Solar magnetic flux tubes of different filling factors were heated with adiabatic and radiatively damped …
