Overview Asian anticyclone is the dominant circulation feature in the

UTLS during NH summer. Asian monsoon is a critical factor in the global troposphere-to-stratosphere transport. It has significant impact on UTLS water vapor budget , and is also an efficient transport pathway for anthropogenic emissions to get into the stratosphere 

Many studies used satellite data and models, which do not provide enough details for characterizing the transport process. There is a debate on the roles of convective and synoptic processes in the TST of water vapor

We are presenting the first in situ measurements of ozone/water vapor inside the anticyclone, the data providing information on the structure and strength of the circulation, complements the large scale satellite observations

Summary For the first time, H2O and O3 in UTLS were measured

during Asian summer monsoon

Some preliminary analysis:

• some finer and interesting structures

• super-saturation and multi-layer in UT

Much more further analysis combined with satellite data and trajectory model is under way

Comments and suggestions are welcome!

Thank you very much!
