About the figures
The right picture is a simplified sample image on this monitoring page.
Each figure shows statistics for satellite wind speed data
which were pre-processed for JMA global delayed analysis.
This sample is for IR wind speed in upper level of Meteosat-7 used in JMA global analysis
during last 50 days.
Global averages and total observation count are displayed.
The details of each figure are follows.
- 1. Mean of wind speed
-
This figure shows mean of wind speed.
OBS, FG and ANA mean reported wind speed,
first guess and analysis respectively.
- 2. Mean
-
This figure shows mean of departures from reported wind speed (OBS) and
those of first guess (FG) or analysis (AN).
- 3. Standard deviation
-
This figure shows standard deviation of departures and reported wind speed.
- 4. Number of observations
-
This figure shows data count of observations which were pre-processed for JMA global analysis.
n_all means number of all pre-processed data.
n_used means number of assimilated data in an analysis.
n_displayed is equal to n_all in case of "All Data", or n_used in case of "Used Data"
