Environmental controls on isolated convection during the Amazonian wet season

Leandro Alex Moreira Viscardi, Giuseppe Torri, David K. Adams, and Henrique de Melo Jorge Barbosa

Data sets

Cloud characteristics, thermodynamic controls and radiative impacts during the Observations and Modeling of the Green Ocean Amazon (GoAmazon2014/5) experiment (https://www.arm.gov/research/campaigns/amf2014goamazon) S. E. Giangrande et al. https://doi.org/10.5194/acp-17-14519-2017

Large-scale vertical velocity, diabatic heating and drying profiles associated with seasonal and diurnal variations of convective systems observed in the GoAmazon2014/5 experiment (http://iop.archive.arm.gov/arm-iop/0eval-data/xie/scm-forcing/iop_at_mao/) S. Tang et al. https://doi.org/10.5194/acp-16-14249-2016

Short summary

We evaluate the environmental conditions that control how clouds grow from fair weather cumulus into severe thunderstorms during the Amazonian wet season. Days with rain clouds begin with more moisture in the air and have strong convergence in the afternoon, while precipitation intensity increases with large-scale vertical velocity, moisture, and low-level wind. These results contribute to understanding how clouds form over the rainforest.
