To investigate the air mass pathways, the most accurate WRF simulation was used as atmospheric conditions for the back-trajectory calculations. It can be easily adapted to work with values of the physical constants and formulas for saturation vapor pressure and condensation temperature that differ from those that Bolton used.In addition, a new formula with three degrees of freedom is found:The previous and new formulas are ranked in terms of the accuracy Of the formulas with a constant adjusted latent heat (one degree of freedom), The maximum errors are not restrained by optimization beyond Finally, we stress that all the accuracies given above are relative to the results from numerical integration of (B25). The ABLH will be determined below the top limiter altitude using Haar wavelet (HM) and the curve fitting method (CFM). Net cloud radiative forcing changes sign from negative in the warm season, to positive in the cold season, when reflective snow reduces the negative SWCF below the positive LWCF.
The diurnal variations in the ABLH determined from HM and CFM on four selected cases show good agreement with a mean correlation coefficient higher than 0.99 and a mean absolute bias of 0.22 km. Traditionally, the low-tropospheric air temperature and equivalent potential temperature (θ e) play crucial roles in the generation of monsoon precipitation through the following mechanisms: 1. The accuracy Steps 8–10 are similar for a formula with only one parameter The method is quite general. (B38) and (B39) are not easily reconciled with an imitation first law. This key radiative forcing has not been available previously for climate datasets. Adjusting the adjusted specific heat of water to zero to eliminate the integral term in the entropy formulation and Kirchoff’s equation makes the specific heat of water vapor negative (or zero if the formula uses a constant latent heat). Select article types you want to add to your filter. Cloud layers are identified by looking for the rapid increase and sharp attenuation of the signal combined with the relative increase in the signal. A total of 2608 dropsondes from 42 named TCs in the Atlantic basin from 1998 to 2017 are used in the composite analyses. An artificial increase in latent heat, (The highly accurate Eqs.

This study presents the climatological characteristics and physical mechanisms of Guinea Coast precipitation in June. The Hydrometeorological Sandbox - École de technologie supérieure (HYSETS) is a rich, comprehensive and large-scale database for hydrological modelling covering 14425 … In the northernmost subregion, Pacific air masses as well reached the Andes highlands with rather low frequencies regardless of the season (2–12%), but with a moisture contribution comparable to the eastern trajectories. For RL in the morning, the altitude limiter is the greatest positive gradient altitude below the RL top. These WRF simulations further revealed that the location of the inter-tropical convergence zone (ITCZ), as well as the precipitation over the Andes Mountains were better reproduced. The results show that the axisymmetric inflow layer depth, the height of maximum tangential wind speed, and the thermodynamic mixed layer depth are all shallower in more intense TCs. Near-surface atmospheric front, depicted by steep ∂ θ e ∂ y , corresponds to … Equivalent Potential Temperature The equivalent potential temperature, θ e, is the potential temperature that would result if all of the water in the air parcel were condensed and rained out by raising the air upwards and then lowering the air parcel to the surface dry adiabatically. The key reason is that trained observers made hourly estimates of the opaque cloud fraction that obscures the sun, moon, or stars, following the same protocol for 60 years at all stations. To assess model uncertainties according to the initial and lateral boundary conditions (ILBCs), the effects of spectral nudging and different driving fields on regional climate modeling were tested.
Atmospheric moisture pathways to the highlands of the tropical Andes Mountains were investigated using the Weather Research and Forecasting (WRF) model, as well as back-trajectory analysis. Select feature papers you want to add to your filter. Cross-sections of the equivalent-potential temperature as an indicator of the moisture and energy content of the atmosphere revealed a downward mixing of the moisture aloft, which was stronger in the southern subregion.
