The Pacific Storm Track

The Convection associated with the synoptic scale activity along the storm track is shown in this short time sequence ( every 8 hours over 64 days) animation.

The eddy activity along the storm track has been simulated without the standard moist parameterizations. Actual individual clouds are explicitly resolved in these runs using explicit moist convection in the non hydrostatic compressible hemispheric model ZETANC. The animation shows only a very small portion of the total integration. The integrated column of liquid water is shown in gray.

The domain shown is 145 degrees in longitude and from 3S to 83.5N in latitude, 25km in heigth.

The numerical domain has been done in various resolutions: 435Xx361, 871x723 and 1742x1446 points in the horizontal and 56 layers in the vertical, the stretch vertical coordinate has DZ min=98m. and DZ max =1700m. The minimun Dx=3.7km, the Dx, Dy~20km, 10km and 5km in the middle of the domain (40 Lat.)
