ITCZ mission: Mission incomplete due to engine failure. We completed the first leg of the ITCZ Pattern 12 to 8 N along 93W. We dropped 7 ocean probes (1 AXCTD fail), and 5 GPS-dropsondes (no failures). Surface winds were primarily from the south with a very small component from the east. Almost no white caps were seen. Flight level winds were south-westerlies. We encounter only one convective spot while in this leg. core (mid 40 DBZ) hight ~8km, anvil ~10km.
