## Time series of statistics on satellite wind

### 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"
