Abstract
Physical oceanography of the Bay of Bengal and Andaman Sea is reviewed for the first time. All available information for over 50 years is consolidated in this review. To begin with, information on peripheral or related aspects of climate of the hinterland, such as pressure, rainfall, storms, winds, sunshine etc., are presented. The Bay of Bengal and Andaman Sea are divided into two regions, viz., the coastal belt and the opean ocean areas, on the basis of large differences in water properties. Considerable variation in salinity and density exists all over the coastal areas due to abundant freshwater discharges, especially during the rainy months. The coastal circulation is mainly driven by river runoff and wind thrust and is influenced by branches of the Equatorial Current system. Strong wind-driven upwelling and sinking are seen along the eastern Indian coast. The surface circulation system in the Bay of Bengal and Andaman Sea can be divided into three gyres, viz., (a) the northwestern gyre, (b) the large gyre in the southern Bay of Bengal and (c) the Andaman gyre. Gyres are noted also at 500 m and 1000 m. The net water exchanges [Evaporation (E) + Precipitation (P) + Runoff (R)] at surface, for the whole area north of 5 degrees N are -11.5 cm and + 63.7 cm during the winter monsoon and summer monsoon, respectively. The net water transports across 6 degrees N between surface and 1250 m, are found to be -79 x 10 sup(12) m sup(3) and + 129 x 10 sup(12) m sup(3) for winter monsoon and summer monsoon periods, respectively. High salinity water masses from the Red Sea, Persian Gulf and eastern and southern Arabian Sea flow into the Bay of Bengal and play an important role in its water structure. A strong gradient of surface temperature is observed during winter (25.5 to 28.5 degrees C) from the head of the Bay to 5 degrees N; similarly for salinity (21.0 to 34.5 ppt) during summer. Variation in mixed layer thickness is greater during summer (about 25 to 100 m) and less during the winter (60 to 100 m). Abyssal water flows and properties are least studied in the Bay of Bengal

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
