Weather GENERAL OVERVIEW

The weather situation for 0000 UTC, Wednesday, April 11 is shown in the 24 hour
forecast depiction . The frontal boundary presently approaching the northern
Yellow Sea will have moved toward the SE and passed the Cheju area according to
present expectations. Dusty conditions will prevail over the Yellow Sea, and
cloud amounts and depths will be limited. The frontal zone will continue to move
toward the ESE, and frontal-passage conditions could prevail in the vicinity of
Iwakuni at the expected return time of the C-130.

The situation at 0000 UTC on Thursday, April 12 is shown here. The frontal
boundary discussed above will have passed southern Japan, bringing high surface and
column dust amounts to a broad region north of 30 N. Scattered clouds are
expected behind this frontal boundary, and surface winds from the NW at both the
ship's location and the area around Cheju. Increasing cloudiness as the day goes
on is also possible in the northern Yellow Sea area, caused by the development
of an elevated low pressure area.

DISCUSSION

Propagating disturbances along the front could change its orientation and
significantly alter the weather in the area. This is unlikely to be a concern until after
Wednesday evening, and we will closely monitor both this situation and the
development of a rapidly-advancing system in north central China shown
schematically on the 48 hour forecast above.

SUMMARY

Conditions are expected to be generally favorable for the C-130 flight
planned for Wednesday, April 11. It is anticipated that the aircraft will
encounter strong winds and the potential for both turbulence and precipitation during its
passage through the frontal zone. It is anticipated that the Twin Otter would
fly next on Thursday, April 12, and it is very likely that aerosol plumes of interest will be
accessible then, both to the Twin Otter and the C-130.
