TLDR
A conceptual model is proposed that explains this apparent dichotomy of pristine tropical clouds with low CCN concentrations rain out too quickly to mature into long-lived clouds and heavily polluted clouds evaporate much of their water before precipitation can occur.Abstract:
Aerosols serve as cloud condensation nuclei (CCN) and thus have a substantial effect on cloud properties and the initiation of precipitation. Large concentrations of human-made aerosols have been reported to both decrease and increase rainfall as a result of their radiative and CCN activities. At one extreme, pristine tropical clouds with low CCN concentrations rain out too quickly to mature into long-lived clouds. On the other hand, heavily polluted clouds evaporate much of their water before precipitation can occur, if they can form at all given the reduced surface heating resulting from the aerosol haze layer. We propose a conceptual model that explains this apparent dichotomy.read more

Climate Impacts of the Biomass Burning in Indochina on Atmospheric Conditions over Southern China
TL;DR: In this paper, the authors evaluate impacts of biomass burning in Indochina during April 2013 on atmospheric conditions in southern China using WRF-Chem sensitivity simulations, and show that the atmosphere becomes drier and hotter under the aerosol radiative effect.

Spatial–temporal patterns of cloud-to-ground lightning over the northwest Iberian Peninsula during the period 2010–2015
TL;DR: In this article, the spatial-temporal patterns of cloud-to-ground (CG) lightning covering the period 2010-2015 over the northwest Iberian Peninsula were investigated using three main methods: the circulation weather types developed by Jenkinson and Collison, the fit of a generalized additive model (GAM) for geographic variables, and the use of a concentration index for the ratio of lightning strikes and thunderstorm days.

TL;DR: In this article, the authors discuss the importance of water quality aspects and floodplain and flood risk management in integrated river basin management (IRBM) and show that water quality and flood risks are two distinct issues in planning procedures and decision-making processes.

Characteristics of Ultrafine Particles and Their Relationships with Meteorological Factors and Trace Gases in Wuhan, Central China
TL;DR: In order to reveal the characteristics of ultrafine particles in central China, which makes up the sparse research in industrial cities of a developing country, particle number concentrations (PNC) together with meteorological parameters and concentrations of trace gases were measured over one year in Wuhan as mentioned in this paper.

Aerosols, climate, and the hydrological cycle
TL;DR: Human activities are releasing tiny particles (aerosols) into the atmosphere that enhance scattering and absorption of solar radiation, which can lead to a weaker hydrological cycle, which connects directly to availability and quality of fresh water, a major environmental issue of the 21st century.

Global indirect aerosol effects: a review
Ulrike Lohmann,Johann Feichter +1 more
TL;DR: In this article, the effects of aerosols on the climate system are discussed and different approaches how the climatic implications of these effects can be estimated globally as well as improvements that are needed in global climate models in order to better represent indirect aerosol effects are discussed.

Climate Effects of Black Carbon Aerosols in China and India
TL;DR: A global climate model used to investigate possible aerosol contributions to trends in China and India found precipitation and temperature changes in the model that were comparable to those observed if the aerosols included a large proportion of absorbing black carbon (“soot”), similar to observed amounts.
