The
NCEP Climatology overestimates the Net Heat Loss for the North
|
|
Atlantic
Region due to overestimation of Latent and Sensible Heat
|
|
Loss
terms and underestimation of Shortwave Gain term.
|
|
|
| • |
This
overestimation is leading to spurious results in the Low NAO
|
|
Model
simulation.
|
|
|
| • |
Functional
regression is used resolve the overestimation in NCEP
|
|
Climatology
as follows:
|
|
|
| • |
Slope
(m) and Intercept (y) are determined for each month using the
|
|
SOC
and NCEP climatologies for 1980-1993 (High NAO)
|
|
|
|
• |
SOC(high
NAO) = m*NCEP(high NAO) + y
|
|
|
|
• |
m
and y are used to adjust the NCEP Climatology for 1958-
|
|
|
1971
(Low NAO)
|
|
|
|
• |
Predicted
NCEP (low NAO) = m*NCEP(low NAO) y, also
|
|
|
|
• |
Predicted
NCEP (high NAO) = [SOC(high NAO)-y] / m
