The NP index is defined to measure interannual to decadal variations in the atmospheric circulation. The dominant atmosphere-ocean relation in the North Pacific is one where atmospheric changes lead changes in sea surface temperatures by one to two months. However, strong ties exist with events in the tropical Pacific, with changes in tropical Pacific SSTs leading SSTs in the north Pacific by three months. onGoing Phillips, Adam UCAR/NCAR - Climate and Global Dynamics Laboratory Associate Scientist asphilli@ucar.edu pointOfContact NETCDF Dataset theme Resource Type 2017-05-10 publication DataCite originator EARTH SCIENCE > CLIMATE INDICATORS > ATMOSPHERIC/OCEAN INDICATORS > TELECONNECTIONS > NORTH PACIFIC PATTERN > NP GCMD 2017-07-18 revision GCMD originator Dash and its services comply with policies set by UCAR and NCAR.
