The approach assumes a stationary climate and came into use about 75 years ago by the World Meteorological Organization (WMO), which sets standards of methodology.Р”В¬limatological normals are indispensable planning tools in a wide variety of industries.

Used by meteorological organizations around the world for analyzing climate conditions, climate normals are average values of temperature and precipitation over a period of time, typically 30 years, and are updated approximately every 10 years. It will be highlighted in a forthcoming issue of the Bulletin of the American Meteorological Society (BAMS). The article, currently published online and in press for print publication, has been designated as a РІР‚СљPaper of NoteРІР‚Сњ by the American Meteorological Society (AMS). РІР‚СљThis new product can assist stakeholders in planning for a broad array of possible ENSO impacts in a changing climate.РІР‚Сњ РІР‚СљIn this study, we add composites of ENSO impacts to the OCN in order to provide users with a picture of what climate conditions may look like when a particular phase of ENSO occurs or is forecast by NOAAРІР‚в„ўs Climate Prediction Center,РІР‚Сњ the scientists state. The new ENSO Climate Normals are introduced in an article published online by the Journal of Applied Meteorology and Climatology, authored by scientists from NCEI and the Cooperative Institute for Satellite Earth System Studies (CISESS).

The new averages also consider an optimal climate normal (OCN) to account for climate change impacts and align the basis of the normals with the most recent climate conditions. However, over the continental United States, El NiР“В±o and La NiР“В±a events are each associated with areas that are colder-than-normal or warmer-than-normal, as well as areas that are drier-than-normal or wetter-than-normal. Globally, El NiР“В±o leads to a warming effect, while La NiР“В±a contributes to cooler conditions. These primarily take into account the influence of El NiР“В±o, La NiР“В±a, and climate change impacts.Р”В®l NiР“В±o and La NiР“В±a events are part of the ENSO cycle, which affects weather and climate conditions worldwide. To enhance the usefulness of these averages, a new set of ENSO (El NiР“В±oРІР‚вЂњSouthern Oscillation) Climate Normals has been developed for the contiguous United States by NOAA NCEI. Many scientific, engineering, and economic activities rely on conventional РІР‚Сљclimate normalsРІР‚Сњ-30-year averages-as a benchmark of climate conditions across the United States. Scientists have developed new temperature and precipitation averages that take into consideration continuing fluctuations and trends in the U.S.
