Abstract: Based on the monthly average sea surface temperature(SST) data of MODIS-Terra climatology from 2000 to 2017, this paper tested the temperature front in the East Indian Ocean monsoon zone, and calculated the number of fronts, the average intensity and the centerline length of each front statistically. Based on the annual SST data from 2000 to 2017, the annual variation of the typical temperature front represented by the GangesBrahmaputra Estuarine front and the Java Island front was studied. It was found that in March and April, the front of the East Indian Ocean monsoon zone was the weakest with the least number; during the period of May to October, the temperature fronts of 5°-15°N and 5°-15°S appeared and developed. In December, January and February, the northern front developed and matured. There were five temperature fronts in the study area: the GangesBrahmaputra Estuarine front, the Java Island front, the Palk Strait front, the East Ceylon Front and the Irravadi Estuarine front. The northernmost GangesBrahmaputra Estuarine front was present throughout the year, and the length of the northeast monsoon period was longer and stronger; the Java Island front existed from April to November, the southwest monsoon period was stronger, the length and the number of front points were also at a high level; the other fronts mainly occured during the prevailing period of the southwest monsoon, and the changes in intensity and length were relatively small. The annual variation of the spatial position of the two typical temperature fronts was small, and the annual variation of the average intensity of the GangesBrahmaputra Estuarine front was greater than 0.03 ℃/km, and the change in length was relatively small. The change of the average intensity of the Java Island front was relatively stable, while there were significant variations in the number of front points and the length of the centerline.
