PSL Web Products and Tools: Climate/Weather Topics

PSL has created a set of web products and tools that we have found useful in our research. The following are sites with useful web links for selected topics.


Atmospheric Rivers
Atmospheric Rivers (AR) are relatively narrow regions in the atmosphere that are responsible for most of the horizontal transport of water vapor outside of the tropics. PSL studies them to better understand their potential impacts.
Changes in Climate Extremes
Results from climate model simulations of temperature and precipitation extremes for the 20th and 21 centuries.
El Niño/La Niña (ENSO)
Current conditions, historical climate and weather relationships and PSL ENSO related research topics.
The Madden Julien Oscillation (MJO)
Detailed description of the phenomena along with the current conditions, forecasts and how the MJO is related to current weather/climate around the Earth.
Boulder Colorado Climate and Weather Resources
Historical weather, interesting weather events, records and regional climate and weather information.
Interesting Radar images
A collection of radar pictures from interesting weather events like Kelvin Helmholtz waves, thunderstorms and mountains waves.
