Even before Tropical Storm Barry made landfall in Louisiana on Saturday, July 13, 2019 it had already dropped a lot of rain on the state. Using satellite data, NASA created a map that shows areas that are likely flooded.
The duration of floods can be determined by river flow, precipitation and atmospheric blocking. Now an international team of researchers led by Nasser Najibi and Naresh Devineni at The City College of New York is offering a novel physically based Bayesian network model for inference and prediction of flood duration. The model also accurately examines the timescales of flooding.
The Eastern Pacific Ocean generated the fourth tropical cyclone of the hurricane season on July 13 and by the next day, it had already weakened into a remnant low pressure area.
Barry, now a tropical depression, continues moving slowly north through Arkansas and rainfall and flooding remains a concern. NASA-NOAA's Suomi NPP satellite passed over the south central United States yesterday, July 14 and captured a visible image of then Tropical Storm Barry.
A new study says that the tropical forests of Western Equatorial Africa (WEA) -- which include significant stands of Intact Forest Landscapes (IFLs) -- are increasingly coming under pressure from logging, poaching, and associated disturbances.
Non-native parrots can cause substantial agricultural damage and threaten native biodiversity. While substantial evidence of negative impact in Europe is currently lacking, there are numerous already established wild populations. A pan-European team of researchers, conservationists, wildlife managers and policy-makers worked together as part of an EU COST Action: ParrotNet, to conclude that measures to prevent parrots from invading new areas are paramount for limiting future harm. Their study is published in the open-access journal NeoBiota.
A new study published in Environmental Science and Policy shows that without adequate and focused policies, many households will rely on air conditioners to adapt to climate change, thus generating even more greenhouse gas emissions.
Preliminary evaluation suggests that FGOALS-f3-L can capture the basic patterns of atmospheric circulation and precipitation well, and these datasets could contribute to the benchmark of current model behaviors for the desired continuity of CMIP. Analysis of these datasets will also be helpful in understanding the sources of model biases and be of benefit to the development of climate forecast systems
Strong volcanic eruptions, especially when a super volcano erupts, will have a strong impact on ozone, and might interrupt the ozone recovery processes.
Tropical Storm Barry made landfall mid-day on July 13, 2019, but infrared satellite imagery from NASA early on July 14 continued to show the heaviest rainmaking storms were still off-shore. NASA's Aqua satellite analyzed cloud top temperatures in the storm which gave an indication of the storm's strength.
