Consequences of Sampling Error
| Top: mean SLP, sample
covariance between SLP everywhere and point in East Asia |
|
| 2nd: same for 400 member ensemble. |
|
| 3rd: function that is 1 at ob location,
tapers to zero several thousand km away. |
|
| 4rd: 25 member covariance multiplied by
taper function (looks more like 400 member covariance). |
