“…3a). A climatological pattern of vertical O 3 distribution presents the uniquely elevated O 3 concentrations in the UTLS region (Liu et al, 2013). The large-scale convections of Typhoon Hagibis were fully developed and well organized with strong uplifts reaching to the UTLS around 100 hPa and consecutively downward flows to the surface level over XQR (Fig.…”

Abstract. A high O 3 episode with the large increases in surface ozone by 21-42 ppbv and the nocturnal surface O 3 levels exceeding 70 ppbv was observed in the region between Xiamen and Quanzhou over the southeastern coast of China during 12-14 June 2014, before the Typhoon Hagibis landing. Variations in the surface O 3 , NO 2 , CO and meteorology during the Typhoon Hagibis event clearly suggest a substantial impact of the peripheral downdrafts in the large-scale typhoon circulation on such an O 3 episode excluding the contributions of photochemical production and the horizontal transport. The influence of vertical O 3 transport from the upper troposphere and lower stratosphere (UTLS) region on high surface O 3 levels is further confirmed by a negative correlation between surface O 3 and CO concentrations as well as dry surface air observed during the O 3 episode. This study provides observational evidence of typhoon-driven intrusion of O 3 from the UTLS region to surface air, revealing a significant effect of such a process of stratosphere-troposphere exchange (STE) of O 3 on tropospheric O 3 and ambient air quality.

“…Ozone variations over recent decades exhibit not only strong trends, forced by changes in ozone-depleting substances superimposed on a changing climate, but also interannual variability influenced by various external and internal climate forcings (e.g., Manney et al, 1994;Müller et al, 1994Müller et al, , 2005Weiss et al, 2001;Hadjinicolaou et al, 2002;Tian and Chipperfield, 2005;Austin et al, 2006Austin et al, , 2010Eyring et al, 2010;Liu et al, 2011Liu et al, , 2013Douglass et al, 2014). Ozone variations can change the amount of harmful solar ultraviolet rays reaching the Earth's surface (Kerr and McElroy, 1993) and even influence climate (Forster and Shine, 1997;Thompson et al, 2011;Li et al, 2016;Xie et al, 2016).…”

Abstract. Using satellite observations, reanalysis data, and model simulations, this study investigates the effect of sea surface temperature (SST) on interannual variations of lower-stratospheric ozone at southern high latitudes in austral spring. It is found that the SST variations across the East Asian marginal seas (5 • S-35 • N, 100-140 • E) rather than the tropical eastern Pacific Ocean, where ENSO occurs, have the most significant correlation with the southern high-latitude lower-stratospheric ozone changes in austral spring. Further analysis reveals that planetary waves originating over the marginal seas in austral spring can propagate towards southern middle to high latitudes via teleconnection pathway. The anomalous propagation and dissipation of ultra-long Rossby waves in the stratosphere strengthen/cool (weaken/warm) the southern polar vortex, which produces more (less) active chlorine and enhances (suppresses) ozone depletion in the southern high-latitude stratosphere on one the hand and impedes (favors) the transport of ozone from the southern middle-latitude stratosphere to high latitudes on the other. The model simulations also reveal that approximately 17 % of the decreasing trend in the southern highlatitude lower-stratospheric ozone observed over the past 5 decades may be associated with the increasing trend in SST over the East Asian marginal seas.

“…With the above-mentioned methods, horizontal data gaps can be reduced without spatial interpolation. Several investigations have used this technique in the stratosphere, where O 3 and N 2 O/NO y are of primary importance (Bacmeister et al, 1999;Morris et al, 1995;Liu et al, 2013). Here we will make use of this technique even in the mesosphere and studying water vapor in more detail and its relation to dynamics.…”

Trajectory mapping of middle atmospheric water vapor by a mini network of NDACC instruments

Abstract.The important task to observe the global coverage of middle atmospheric trace gases like water vapor or ozone usually is accomplished by satellites. Climate and atmospheric studies rely upon the knowledge of trace gas distributions throughout the stratosphere and mesosphere. Many of these gases are currently measured from satellites, but it is not clear whether this capability will be maintained in the future. This could lead to a significant knowledge gap of the state of the atmosphere. We explore the possibilities of mapping middle atmospheric water vapor in the Northern Hemisphere by using Lagrangian trajectory calculations and water vapor profile data from a small network of five ground-based microwave radiometers. Four of them are operated within the frame of NDACC (Network for the Detection of Atmospheric Composition Change). Keeping in mind that the instruments are based on different hardware and calibration setups, a height-dependent bias of the retrieved water vapor profiles has to be expected among the microwave radiometers. In order to correct and harmonize the different data sets, the Microwave Limb Sounder (MLS) on the Aura satellite is used to serve as a kind of traveling standard. A domain-averaging TM (trajectory mapping) method is applied which simplifies the subsequent validation of the quality of the trajectory-mapped water vapor distribution towards direct satellite observations. Trajectories are calculated forwards and backwards in time for up to 10 days using 6 hourly meteorological wind analysis fields. Overall, a total of four case studies of trajectory mapping in different meteorological regimes are discussed. One of the case studies takes place during a major sudden stratospheric warming (SSW) accompanied by the polar vortex breakdown; a second takes place after the reformation of stable circulation system. TM cases close to the fall equinox and June solstice event from the year 2012 complete the study, showing the high potential of a network of ground-based remote sensing instruments to synthesize hemispheric maps of water vapor.
