To determine the impact of dynamic and aerosol processes on marine low clouds, we examine the seasonal impact of updraft speed w and cloud condensation nuclei concentration at 0.43 % supersaturation (NCCN0.43%) on the cloud droplet number concentrati

Bastante difundido nos Estados Unidos, o termo “ficção especulativa” indica uma extensa produção literária na qual conjunturas, tempos e espaços alternativos têm sido imaginados, resultando em um corpus literário rico de significados. Est

Aerosol–cloud interactions contribute to the large uncertainties in current estimates of climate forcing. We investigated the effect of aerosol particles on cloud droplet formation by model calculations and aircraft measurements over the Amazon and

Quantifying the precipitation within clouds is a crucial challenge to improve our current understanding of the Earth's hydrological cycle. We have investigated the relationship between the effective radius of droplets and ice particles (re) and preci

The high variability of aerosol particle concentrations, sizes and chemical composition makes their description challenging in atmospheric models. Aerosol–cloud interaction studies are usually focused on the activation of accumulation mode particle

We present a linear-time algorithm that computes in a given real interval the number of eigenvalues of any symmetric matrix whose underlying graph is unicyclic. The algorithm can be applied to vertex- and/or edge-weighted or unweighted unicyclic grap

Abstract Recent investigations show that the thermal spectral function of heavy b b ¯ $$ b\overline{b} $$ and c c ¯ $$ c\overline{c} $$ vector mesons can be described using holography. These studies consider a bottom up model that captures the heav

We have investigated how aerosols affect the height above cloud base of rain and ice hydrometeor initiation and the subsequent vertical evolution of cloud droplet size and number concentrations in growing convective cumulus. For this purpose we us

Abstract The finite temperature spectrum of pseudo-scalar glueballs in a plasma is studied using a holographic model. The $$ 0^{-+}$$ 0-+ glueball is represented by a pseudo-scalar (axion) field living in a five dimensional geometry that comes from a
