Climate Change: Precipitation

This simulation shows a comparison between present day (1990) and future (2090) precipitable water in the Earth’s atmosphere using an RCP8.5 emissions scenario. Movies  Movie File (.mov, 1920×1080, 236MB) Images Science Credits This simulation was made possible because of the large number of individuals both from within NCAR and the many outside collaborators who have…

Negative NAO Triggered by Stratospheric Sudden Warming

Seasonal forecast for winter of 1997/1998 with 46LCAM (Ensemble member with a sudden stratospheric warming). This is a 4 month forecast of surface geopotential height anomalies (shown with surface relief and contour lines) and surface temperature anomalies (shown with a color gradient). The forecast starts on Dec 1, 1997, and goes through the end of…

Global weather simulated by a cloud-resolving weather prediction model

The global weather from 20 October – 4 November 2012, simulated by a cloud-resolving weather prediction model Model: MPAS – Variable: Outgoing Longwave Radiation Science: The complex evolution of multiscale cloud systems illustrates the myriad of weather phenomena that populate our atmosphere. Features of interest include the diurnal cycle of convection over central Africa and…

Ocean impact on atmospheric oxygen and carbon dioxide

The ocean breathes: a map of oxygen and carbon dioxide variations in the atmosphere due to air-sea gas exchange, stirred by winds. The ocean absorbs CO2 and releases O2 in the summer hemisphere, primarily due to photosynthesis (and warming, for O2) at the surface; the reverse happens during winter when the surface cools and deep…

Surface Ozone Concentrations on the Colorado Front Range

This animation shows simulated hourly surface ozone concentrations during the 2014 FRAPPÉ campaign. The simulations have been performed with the Weather Research and Forecasting (WRF) Community Multiscale Air Quality (CMAQ) model. The simulations have been conducted with a 4 km x 4 km grid horizontal resolution and show the frequent occurrence of high ozone pollution…

Surface Temperatures from Climate Change vs. Geoengineering

This visualization describes temperature changes relative to years 2015-2024 from unabated climate change (RCP8.5) and stratospheric sulfate aerosol geoengineering (using feedback) simulated by a state-of-the-art coupled earth system model. Geoengineering, often using stratospheric sulfate aerosols, is discussed as a potential means of deliberately offsetting some of the effects of climate change, such as rising temperatures.…

Modelling The Indonesian Throughflow

Rising ocean temperatures have given rise to coral bleaching events at higher rates than have been seen in observed history. Researchers at the National Center for Atmospheric Research are studying how effectively coral reef ecosystems can repopulate each other after bleaching events through a metric called Potential Connectivity. In this visualization, we observe a state…
