On the role of warm rain clouds in the tropics
… LWP anomalies occur with positive low-level moistening and heating anomalies prior to TD events, but that there is little variation in the properties of non-raining clouds. The moistening by these clouds is also shown to influence the generation of convective available potential energy (CAPE) …

A numerical model study about the impacts of dry air on tropical cyclone formation
… moisture advection plays the dominant role in moistening the free atmosphere. Persistent mid-level drying is shown to suppress deep convection and reduce moisture supply to the free atmosphere. Three-dimensional trajectory analysis based on the numerical simulation of Fay suggests that dry air …

Observed microphysical characteristics and inferred thermodynamic processes contributing to the structure, evolution, and maintenance of nocturnal elevated mesoscale convective systems
… sustained precipitation in the observed regions. Moistening associated with sublimation occurred at a greater rate in the subsaturated air above the ML than the rate of evaporative moistening below the ML due to changes in particle concentrations accompanying increases in particle fall velocity …

A numerical modeling investigation of entrainment in cumulus congestus clouds and its effects upon precipitation
… generations of convection. Substantial moistening of the locally entrained air into the later generations served to protect the clouds from dilution and enhanced the warm rain process.

Radiative feedbacks in tropical organized convection and the Madden-Julian oscillation
… driven circulation and the associated moistening effects in the MJO can be derived in a weak-temperature-gradient framework and a linear baroclinic model. The result suggests that LW heating moistens the MJO more efficiently than the total apparent heat source, while shortwave (SW) …

Understanding precipitation, cold pools, and cloud arcs in the tropics
… to quantify and understand the role of layer moistening (on updrafts) and drying (on evaporative cooling and downdrafts) and subsequent behavior of cold pools and longevity and structure of convective arcs. It was found that surface relative humidity and wind speed in the lowest 2 km have the …

The role of soil moisture on summer climate simulations over southern Africa
… climate to soil moisture forcings by drying or moistening the land surface using a regional climate model version 3, RegCM3. The sensitivity and response capabilities to soil moisture perturbations of the model are investigated. This includes identification of regions that may be influenced …

Impacts of reducing shipboard NOx̳ and SOx̳ emissions on vessel performance
… exhaust gas recycle (EGR) and scavenge air moistening (SAM). The published performance impacts are applied to the vessels traveling on a hypothetical route comparing new transit times and increased fuel consumption.

On the paradox of convectively-coupled waves
… that shallow convection is fundamental to moistening as well as the low-level static stability, both of which have a significant effect on convection and indirectly, the forcing of convectively coupled waves.

An Ensemble Numerical Modeling Study of Alantic Basin Hurricane Intensification
… an increased warm core, a raised tropopause and moistening of rain bands with an increased forecast intensity. Perturbed initial conditions show a linear model response for small perturbations but also signs of non-linearity at large perturbations, indicating that these sensitivity patterns are …

The Madden-Julian Oscillation and Convective Aggregation
… inclusion of an additional physical effect, the moistening of the interior flow due to convergence in the boundary layer, gives behaviour that is more similar to the observed MJO in both spatial structure and propagation speed. The model derived and analysed in this thesis gives insight into the …

Midlatitude Storm Track Response to Increased Greenhouse Warming
… to subtropical drying and higher latitude moistening. This dissertation is to investigate the storm track response to increased greenhouse warming and the dynamical mechanisms driving the changes in the storm tracks. First, by analyzing the eddy statistics simulated in the Geophysical Fluid …
