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: Yan.Xue@noaa.gov.
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).
