Ozone Hole Collage The CPC compiles data on historic and current atmospheric and oceanic conditions in the oceans, data on climatic patterns such as the North Atlantic and Pacific Decadal Oscillations and stratospheric ozone and temperature data.

Tropical Pacific - The CPC monitors the tropical Pacific sea surface temperatures (SST) and winds as they play a major role in influencing global climate.

  • Climate Diagnostics Bulletin - The Monthly Bulletin provides a technical discussion of current oceanic and atmospheric conditions in the tropical Pacific as well as the forecast together with the data on winds, sea surface temperatures, sea level pressures, water vapor and other variables.

  • Preliminary Climate Bulletin Figures - Latest monthly Tropical Pacific sea surface temperatures, wind, and outgoing longwave radiation maps from the upcoming Climate Diagnostics Bulletin.

  • Monthly Atmospheric and SST Indices - Data and time series for monthly atmospheric and SST index values for winds, sea level pressure, southern oscillation index (SOI), equatorial SOI, sea surface temperatures, temperature anomalies, and outgoing longwave radiation.

  • Weekly ENSO Update - Figures depicting SST, OLR, atmospheric circulation and sub-surface ocean structure across the tropical Pacific, updated on Monday.

  • Monitoring Tropical Intraseasonal Oscillations - Tropical rainfall exhibits strong variability on sub-seasonal time scales of 30 to 60 days. The intraseasonal oscillations have an important impact on winter storminess and temperatures over the U.S. During the summer, these oscillations have a modulating effect on hurricane activity in both the Pacific and Atlantic basins.

Global Ocean Analysis - The CPC uses the global ocean analysis provided by the NCEP's Global Ocean Data Assimilation System to monitor the current and historical conditions of the state of the global ocean. A "Monthly Ocean Briefing is made around the 7th day of each month to provide the user community a real time assessment of how the state of the global ocean involved recently, what is the interaction with atmosphere, and how model predictions verify. This operational product is useful for climate attributions and climate predictions such as outlooks for ENSO, Hurricane and U.S. drought. The ocean briefing is done through a PPT presentation and conference call. Contact:

Global Precipitation Analysis - The CPC monitors global precipitation with the aid of conventional raingauge observations and remotely sensed precipitation estimates from satellites. It is important to monitor fluctuations in precipitation around the globe since these changes often reflect transitions in the coupled atmosphere-ocean system such as occur during El Niño and La Niña episodes.

Monitoring Hurricane Potential - Sea surface temperatures and wind speed and direction, vorticity, height, and departures from normal not only play a role in hurricane formation but also climate. (Page active June to December).

Northern Hemisphere Teleconnection Patterns - In addition to ENSO, other teleconnection patterns including the North Atlantic Oscillation (NAO), East Atlantic (EA), East Atlantic Jet (EA-Jet), East Atlantic/Western Russia Scandinavia (SCAND), Polar/Eurasia, Asian Summer, West Pacific (WP), East Pacific (EP), North Pacific (NP), Pacific/North American (PNA), Tropical/Northern Hemisphere (TNH), and Pacific Transition (PT) influence global climate patterns. The CPC produces charts of standardized amplitudes, positive phase maps, daily and monthly time series, and an archive of indices dating back to 1950.

Stratospheric Ozone

The CPC produces maps of daily hemispheric ozone, and stratospheric temperature time series.

On-Line Data

The CPC maintains two sites for users with high speed computers to access meteorological and oceanographic data.

  • Global Data Display System - Extensive on-line data base that allows a user to make meteorological and oceanographic plots and download climate and weather data.

  • Reanalysis: Atmospheric Data - The NCEP/NCAR Reanalysis Project is a joint project between the National Centers for Environmental Prediction (NCEP) and the National Center for Atmospheric Research (NCAR). The goal of this joint effort is to produce new atmospheric analyses using historical data (1957 onwards) and to produce analyses of the current atmospheric state (Climate Data Assimilation System, CDAS).
