Coastal Upwelling Ecosystems Analysis. Technical Report 66. Atlas of the JOINT II 1977 Aircraft Winds for the 500 Foot Level

摘要

Maps of winds at 500 ft are presented for twelve (12) individual flights using aircraft data gathered during daytime (l000-1500 L) flights made in March-April-May as part of JOINT II 1977. Details of the data reduction and analysis techniques are discussed. The total wind field is shown by maps of the streamlines and isotachs while the alongshore and onshore components are shown by isotach maps. Maps of the 500 ft winds on the individual flights reveal: (1) the flow is generally steady and parallel to the coast but with onshore flow near the mouth of the Ica River.
