This visualization shows a CESM1 model comparison between a present day (1990) and a future (2090) simulation using a business-as-usual or high emissions scenario, called RCP8.5. Clouds represent six-hourly time steps of total water vapor for one year. Technically speaking, this is the CESM1 model variable, TMQ, defined as the total precipitable water (vertically integrated)…

Droplet Dynamics in Cloud Turbulence
The study of droplet dynamics is a crucial part of cloud physics and involves investigation of each and every droplet’s properties. It is difficult to carry out such investigations using field observations. Small scale simulation is one method to study such phenomena, and visualization of these processes provides a deep and quick understanding. This work…

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…

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…
Read moreGlobal 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…
Read moreOcean 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…

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…

Project Metis: Seasonal Forecasts with Enhanced Ocean and Atmosphere Resolution This visualization shows total accumulation of global precipitation (blue/purple) and the 6-hourly precipitation (yellow/red) between May 1 and Nov 1, 2015. What to look for: Of particular interest are the cyclones that scrawl lines across the map, leaving a visible trail in the total precipitation field. Movies Movie…
