Without having relative humidity, dewpoint, vapor pressure, or water vapor mixing ratio at a level in your data, there isn't much you can do with moisture convergence. The only thing you can do with total column water (which I assume is the same thing as precipitable water), is compute the column total or column average moisture convergence, but that doesn't seem to be useful.<br>
