Meanwhile, before the MJO arriving on 13 Dec., MLD and ILD are quite shallow and BLT is less than 20 m. Whereas, as the MJO arriving 13 Dec., ILD is rapidly increasing from 20 m to 80 m, but very shallow MLD is keeping less than 20 m. Then, BLT is drastically deepening during the MJO passage. This time lag of deepening of ILD and MLD is due to
- like this. This is a time-depth cross section of temperature from 3-hourly CTD observation. Mixed layer depth defined from density difference that is equivalent to 0.2degC is shown by dashed line, and isothermal depth defined from 0.2degC temperature difference is shown by dotted line.
