1. Operational Oceanography/Meteorology
Determining Factors in the Development of Marine Stratus Along the Central Coast
LT Max Salazar

2. Overview
Question: What are the determining factors for the development of marine stratus?
Data: Obtain SST, ambient air temperatures, rawindsonde data and time series data during the Point Sur cruise. Examine satellite imagery from the cruise period.
Methodology
Conclusions

3. Methodology: Stratus vs. Non-stratus events
Will Look at:
GOES-11 imagery, including infrared and HI-RES visual
Plots of temperature and dew point temperature vs. height produced from data obtained from balloon launched rawindsonde
Student accumulated data (Observation sheets)
Temperature, Dew Point Temperature and SST from the time series data

34. Conclusion Changes in air temperature signified the
development/dissipation of marine stratus.
During cases of marine stratus, inversion went up to about meters.
During cases of no marine stratus, inversion went up to a height of 750 meters.
