For instance, a 2010 statistical analysis found a weakening of the AMOC has been continuing since the late 1930s with an abrupt shift of a North-Atlantic overturning cell around 1970. [108] In 2015, a different statistical analysis interpreted a cold pattern in some years of temperature records as a sign of AMOC weakening.
The OPC provides an important role in the production of the National Weather Service Unified Surface Analysis. After the Weather Prediction Center, or WPC, sends out their analysis for the synoptic hour, OPC cuts and stitches the WPC analysis to its area. The National Hurricane Center, or NHC, stitches the analysis from the Honolulu Forecast ...
Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line.
The surface analysis is a manual analysis of surface fronts and pressure over North America and adjacent oceans performed every three hours. The analysis utilizes a variety of weather data in addition to observations of surface weather conditions, such as upper air observations, global satellite imagery, Doppler weather radar, and model mass ...
Surface wind direction and speed is also forecast on this type of chart. Wave prognostic charts show the expected sea state at some future time. [ 2 ] Low-level prognostic charts used by aviators show the forecast between the Earth's surface and 24,000 feet (7,300 m) above sea level over the next two days.
A surface weather analysis for the United States on October 21, 2006. Main article: Surface weather analysis A surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.

A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
Ocean surface topography or sea surface topography, also called ocean dynamic topography, are highs and lows on the ocean surface, similar to the hills and valleys of Earth's land surface depicted on a topographic map. These variations are expressed in terms of average sea surface height (SSH) relative to Earth's geoid. [1]
