The energetics characteristics of the Asian winter monsoon over the Aleutian low area are described using twice daily upper-air observations during a three year period. The area shows the typical energetics features observed for occluded cyclones. However, at the tail end of the winter monsoon, they are distinctly different from energetics patterns reported over source regions and the Kuroshio area. The kinetic energy level is significantly lower, and the energy transformation is much less intense. The cross-isobaric generation and dissipation are roughly balanced. The contribution of baroclinic conversion is secondary as the energy source.
