Indonesia Air Asia 8501: A Meteorological Analysis

Updated: 10 January 2015 (updated upper air analysis and summary).

In the early morning of December 28th, 2014, an Indonesia Air Asia A320, enroute from Surabaya, Indonesia, to Singapore, disappeared from radar screens and radio contact was lost part of the way through its cruise over the Java Sea, just southeast of Pulau Belitung Island. All 162 people on board perished. The crew had performed a deviation off course due to weather, and had requested a climb from FL320 (32,000 ft) to FL380. ATC radar showed the aircraft passing through FL363 (36,300 ft) when radar contact was lost. See here for factual updates on the flight and investigation.

It is purely a statement of observations as I see them and is in no way aimed at interfering with the official investigation.
