NE-NAO - WEEKLY INDICE REVIEW - Legend

official product of... New England NAO

consists of two-parts:

          1. ANALYSIS -
an analyzation of the NAO, AO, & PNA GEFS & Operational GFS Teleconnection Indice Forecasts from NOAA's Climate Prediction Center (CPC). The EPO & WPO GEFS Teleconnection Indice Forecasts from 
NOAA's Earth System Research Laboratory (Physical Sciences Division)
(ESRL/PSD) & NCEP... are also included, as well as the AAO GEFS Indice Forecast from CPC. Each Indice Forecast includes an analyzation of current deviation from normal-mean through use of a color-scale, which is meant to provide a better understanding of "current" trends with each indice.

          2. INTERPRETATION -
an interpretive overview from the author's understanding of the Analysis, which is made-up of 
two-subparts: 

A. EXTENDED OUTLOOK

B. LONG RANGE THOUGHTS

New England (NAO) Region - Massachusetts, Vermont, New Hampshire, Maine, Connecticut, & Rhode Island
           3. This LEGEND is to provide the viewer with a better understanding of
color-scale used during updates of
The NE-NAO - WEEKLY INDICE REVIEW :

neutral - demonstrates a zonal
or de-amplified pattern.

North Atlantic Oscillation (NAO) - This light blue (aqua) shade demonstrates a very weakly or weakly
Negative NAO,
-0.1 Standard Deviation (SD) to -1.5.
This color-scale would also apply to other Teleconnection indices of this deviation from normal-mean. 

Arctic Oscillation (AO) - This true standard blue shade demonstrates a moderately, strongly, or extremely Negative AO, -2.0 Standard Deviation (SD) and greater.
This color-scale would also apply to other Teleconnection indices of this deviation from normal-mean.

Pacific-North American Oscillation (PNA) - This orange shade demonstrates a very weakly or weakly
Positive PNA, +0.1 Standard Deviation (SD) to +1.5.
This color-scale would also apply to other Teleconnection indices of this deviation from normal-mean.

Eastern Pacific Oscillation (EPO) - This true standard red shade demonstrates a moderately, strongly, or extremely Positive EPO, +2.0 Standard Deviation (SD) and greater.
This color-scale would also apply to other Teleconnection indices of this deviation from normal-mean.

          4. New England NAO (NE-NAO) common abbreviations & contractions used:

A. -NAO - demonstrates a general Negative Phase of the North Atlantic Oscillation (NAO) pattern... this contraction would also apply to other teleconnection indices when applicable, such as:
-AO, -PNA, -EPO, -WPO, & -AAO

B. +NAO - demonstrates a general Positive Phase of the North Atlantic Oscillation (NAO) pattern... this contraction would also apply to other teleconnection indices when applicable, such as:
+AO, +PNA, +EPO, +WPO, & +AAO.
