The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Hurricanes & Tropical Storms report focuses primarily on storms and conditions that affect the U.S. and its territories, in Atlantic and Pacific basins. The report places each basin's tropical cyclone activity in a climate-scale context. Key statistics (dates, strengths, landfall, energy, etc.) for major cyclone activity in other basins is occasionally presented. Reports began in June 2002. The primary Atlantic hurricane season (June-November) is covered each year; other months are included as storm events warrant. An annual summary is available from 2002. These reports are not updated in real time.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Global El Niño/Southern Oscillation report describes atmospheric and oceanic conditions related to ENSO, a periodic fluctuation in sea surface temperature (El Niño) and the air pressure of the overlying atmosphere (Southern Oscillation) across the equatorial Pacific Ocean. Each report provides a status statement and descriptions of the following indicators: 1) Sea surface temperatures (SSTs) and mixed-layer conditions; 2) Equatorial zonal winds (U-component winds) and sea-level topography; 3) Outgoing longwave radiation (OLR); and 4) Southern oscillation index (SOI). Reports were written monthly from January 2004 through October 2009 with annually summaries for 2003-2008. As of the October 2009 report, NCDC no longer wrote a separate assessment of the current state of El Niño/Southern Oscillation as part of its monthly climate report. The information is incorporated in the El Niño Diagnostic Discussion produced each month by the NOAA Climate Prediction Center.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - Global Snow & Ice report provides a global view of snow and ice, placing the data into a historical perspective. Because the Northern Hemisphere has the vast majority of the planet's seasonal snow cover, the report focuses on the Northern Hemisphere snow cover extent. In addition to snow cover, sea ice extents in both hemispheres are included. Annual reports are available from 2002 with some monthly reports in 2005 and 2006. Regular monthly reports begin in 2007. Not all topics are covered in each report and level of detail varies.

The State of the Climate is a collection of periodic summaries recapping climate-related occurrences on both a global and national scale. The State of the Climate Monthly Overview - National Snow & Ice report provides an analysis of snow and ice in the United States, placing the data into a historical perspective. Topics include snow cover extent and snowpack; the period of record for snow cover extent is 1967 to the present. Significant events and storms are also covered. Reports are generated monthly for all snow months in the U.S. (October-April, occasionally September and May) beginning with October 2002. Additional annual analyses focused on the July through June Northern Hemisphere "snow season", as opposed to the calendar year, are available beginning in 2008.
