Continuing CFC‐11 emissions will cause additional future stratospheric ozone depletion.

Largest statistically significant ozone depletion occurs in the global and Antarctic spring total column, and global upper stratosphere.

Additional ozone depletion due to continuing CFC‐11 emissions will cause small changes in stratospheric temperature and circulation.

We re‐performed solar constant dependence experiment of Ishiwatari et al. (2007) which was retracted due to a model bug.

We revised the climate regime diagram for gray atmosphere drawn in solar constant ‐ ice line latitude plane.

We confirmed that the snowball state, the partially ice‐covered state, and the runaway greenhouse state coexist for some solar constants.

Criteria to identify valley wind episodes from ground‐based observations were proposed and evaluated.

Interactions between mountain–plain wind and urban breeze were found from surface observations.

The interaction can modulate the reversal times of diurnal mountain–plain winds.

Air parcel back trajectories help explain the pathways for non‐Gaussian temperature distribution tails at select extratropical locations.

Extreme temperatures in locations with non‐Gaussian temperature distribution tails can occur with a range of meteorological mechanisms.

Tail non‐Gaussianity is governed by the proximity of the location to influential geography and climatologically anomalous air source regions.

The lightning protection tower showed no meaningful protection for self‐initiated negative upward lightning.

Self‐initiated negative upward lightning have larger peak value and shorter rise time during initial stage.

Negative upward lightning tend to exhibit pulsation in current waveform under a larger rate of current rise.

Thermospheric neutral density at 500 km altitude lowers by over 80 percent with a high ground‐level carbon dioxide concentration of 890 ppm.

Meeting the 1.5 degrees Paris agreement target limits the reduction in neutral density at 400 km since the year 2000 to around 28 percent.

Objects in LEO will have orbital lifetimes around 30 percent longer at the 1.5 degrees target than comparable objects from the year 2000.

The technique of electric cloud structure estimation based on WRF simulation of a convective event is developed.

A dipole structure with a positive lower layer is typical for the thunderclouds producing intense thunderstorm ground enhancements (TGEs).

Snow and graupel particles are the main charge carriers in the mountain conditions of TGE occurrence.

The fossil fuel contribution and corresponding MAE365 value of WSOC were higher in northern than southern China.

Higher 14C and 13C of WSOC in cold seasons may be related to corn residue burning.

Primary coal combustion emissions and secondary fossil WSOC generated under high NOX conditions increase MAE365 of WSOC in cold seasons.

Elevation‐dependent warming will happen in the future with its magnitude and structure varying with seasons

Surface albedo feedback is the primary contributor to elevation‐dependent warming and the dominant source of uncertainty in its projections.

The projected elevation‐dependent warming depends not only on the driving global climate model but also on the internal model physics.

While anthropogenic influence is lowest in winter, cloud drop number concentrations are close to peak values along with high sea salt levels

Bimodal volume size distributions with a dominant coarse mode peak that shifts to smaller sizes in spring/summer due in part to dust

Extreme pollution events show the sensitivity of remote marine sites like Bermuda to continental outflow of urban emissions, dust, and smoke
