Highly variable refractive conditions over the Persian Gulf and Gulf of Oman are studied during the SHAREM 110. Data collected during SHAREM 110, conducted in February 1995, included the Naval Operational Regional Atmospheric Prediction System (NORAPS), a large data base of upper air profiles, shipboard surface weather observations, and satellite imagery. Four different meteorological regimes occurred; pre-Shamal or Kaus, Shamal, Northeast Monsoon, and a short Shamal event. In addition to discussing the effects of synoptic meteorology on refraction during these periods, topography is also found to be a major factor in influencing refractive variability. The land/sea breeze was also found to be very important in modifying the low level refractive structure, especially in the Gulf of Oman.
