models of the climate

When it comes to images related to climate models, the idea is closely based on any image classification algorithms that are used in ML. Scientists at NERSC have come up with a novel method to identify and establish patterns using a DL technique called Convolutional Neural Network (CNN).

Climate models have suggested that human-caused climate change could cause this cycle to slow, as warmer ocean temperatures and fresh water from melting ice stop water from sinking as it normally would, which would drive the cycle. If that slowdown really does happen, the climates of North America ...

"The SOCRATES project was designed to collect samples and observations to provide new datasets and parameterizations with which to test and improve weather and climate models," Moore explained. Hands-on data collection was necessary to advance understanding of cloud formation over the ...

An international group of researchers have for the first time accurately calculated the effects of aerosols on clouds in a climate model. The team ... The work, which was published in Nature Communications is the start of what the researchers hope will be a push for greater accuracy in climate models. “In the ...

In a new paper, Schneider et al. outline a blueprint for a next-generation climate model that would employ advancements in data assimilation and machine learning techniques to learn continuously from real-world observations and high-resolution simulations. This approach gets at the heart of the ...

The fidelity of global climate models dictates the accuracy of our climate predictions. It is therefore very important to continually improve the parameters that describe the system and determine their transport and mixing. The cost and significant logistical burden associated with making measurements in ...

Wandering greenhouse gas. Climate models need to take into account the interaction between methane, the Arctic Ocean and ice. Date: March 16, 2018; Source: Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research; Summary: On the seafloor of the shallow coastal regions north of Siberia, ...

Industry questions climate models in regulatory fight. Camille von Kaenel, E&E News reporter. Published: Wednesday, March 14, 2018. A trade group for automakers sent federal regulators research that calls into question climate modeling and the effects of global warming as part of its efforts to loosen fuel efficiency rules.

For these studies, concentrating on a small detail in a full climate model is like trying to find a needle in the haystack. It is therefore common practice in such cases to take away the haystack by using simpler climate models. Scientists usually write these models for specific projects. A quote commonly ...

Not all climate models have the same value. A paper led by Professor Francisco J. Tapiador at the University of Castilla-La Mancha argues that as climate models are increasingly used for societal applications, a focus on gauging their reputations in order to prune those not up to industrial-grade quality ...

KOCHI: A paper published in Proceeding of National Academy of Sciences of USA (PNAS) on Tuesday said that there could be a 45% decrease in Indian summer monsoon in the late stages of 21st century. Researchers from the centre for prototype climate modeling, New York University, Abu Dhabi - who ...

Their research, published in Physical Review Letters, could be helpful in developing new climate models that better capture ocean dynamics. The study ... "If you want to simulate hundreds or thousands or years, or if you want something you can incorporate within a climate model that combines ocean and ...

A recent research into global sea level rise has shown sea levels will rise to an average of 26 inches by the end of the century. According to reports, this is happening as a result of thermal expansion of water as influenced by the accumulation of carbon dioxide and the ongoing destabilization of earth's ice ...

An example of observational constraint (or model screening) is the multimodel Atmospheric Chemistry and Climate Model Intercomparison Project study [Shindell et al., 2013], in which five models were selected from nine on the basis of their skill in simulating aerosol optical depth. The five models had a ...

"If you want to simulate hundreds or thousands or years, or if you want something you can incorporate within a climate model that combines ocean and atmospheric dynamics, you need a coarser-grained model or it's just computationally intractable," Fox-Kemper said. "If we understand the statistics of how ...

CORVALLIS, Ore. - In the midst of what has been (until most recently) an unseasonably warm winter in the Pacific Northwest, a comparison of four publicly available climate projections has shown broad agreement that the region will become considerably warmer in the next century if greenhouse gas ...

In addition, the earliest climate models in the 1960s were focused on the atmosphere, but now they take into account land surfaces, sea ice, aerosols, the carbon cycle, vegetation, and atmospheric chemistry. More recently, models have started to incorporate the ways that human behavior shifts in response ...

Years ago, before 2010, the tidal gauge at Virginia Key showed high tide floods maybe twice a year. By 2070, most climate models show it could flood every single day, according to a new report from the National Oceanic and Atmospheric Administration. The remaining models show flooding ever other day ...
