This study examines mechanisms which control heavy snowfalls in the eastern coast of Korea. Previous observational studies have indicated that heavy snowfalls are caused by the advection of cold and dry air over the warm ocean off the eastern coast. Previous studies have not considered the effects of surface heat fluxes on heavy snowfalls. It is li...

... b show the snapshots of cloud-liquid and cloud-ice mass concentration (g m -3 ), re- spectively, in the control run. These snapshots are obtained over the west-east direction and at 15 km in the north-south direction. They are at 13:30 LST which is the time of the maximum snowfall rate and hence, represent clouds at their mature stage. As seen in Fig. 6, clouds are typically cumulus clouds which are trapped in the PBL whose tops are around 1.6 km. The cores of these clouds occupy a portion of the domain and thus cause the inhomogeneous distribution of cloud properties such as cloud mass. In both Figs. 6a and b, the cores are defined as areas which have hydrometeor mix- ing ratios ...

... The warm-low type is thought to be a favorable condition for heavy snowfall. The north-south-oriented highto-low pressure pattern is generally known to promote Kor'easterlies and heavy snowfall (Bae and Min, 2016;Lee et al., 2018), which is the case when Kaema high pressure is supported. When atmospheric blocking (Rex, 1950) restrains this system from propagating to the east, extreme snowfall events (snow depth of 192.6 cm within 9 d) in the Gangwon region could occur (Bae and Min, 2016). ...
Snowfall in the northeastern part of South Korea is the result of complex
snowfall mechanisms due to a highly contrasting terrain combined with nearby
warm waters and three synoptic pressure patterns. All these factors together
create unique combinations, whose disentangling can provide new insights into
the microphysics of snow on the planet. This study focuses on the impact of
wind flow and topography on the microphysics drawing of 20 snowfall events
during the ICE-POP 2018 (International Collaborative Experiment for
PyeongChang 2018 Olympic and Paralympic winter games) field campaign in the
Gangwon region. The vertical structure of precipitation and size distribution
characteristics are investigated with collocated MRR (micro rain radar) and
PARSIVEL (particle size velocity) disdrometers installed across the mountain
range. The results indicate that wind shear and embedded turbulence were the
cause of the riming process dominating the mountainous region. As the
strength of these processes weakens from the mountainous region to the coastal
region, riming became less significant and gave way to aggregation. This
study specifically analyzes the microphysical characteristics under three
major synoptic patterns: air–sea interaction, cold low, and warm low.
Air–sea interaction pattern is characterized by more frequent snowfall and
vertically deeper precipitation systems on the windward side, resulting in
significant aggregation in the coastal region, with riming featuring as a
primary growth mechanism in both mountainous and coastal regions. The cold-low pattern is characterized by a higher snowfall rate and vertically deep
systems in the mountainous region, with the precipitation system becoming
shallower in the coastal region and strong turbulence being found in the layer
below 2 km in the mountainous upstream region (linked with dominant
aggregation). The warm-low pattern features the deepest system: precipitation
here is enhanced by the seeder–feeder mechanism with two different
precipitation systems divided by the transition zone (easterly below and
westerly above). Overall, it is found that strong shear and turbulence in the
transition zone is a likely reason for the dominant riming process in
the mountainous region, with aggregation being important in both mountainous and
coastal regions.

... Temperature and humidity tendencies at each altitude from sequential soundings are obtained and applied to the control run every time step by interpolation in a horizontally homogeneous manner. These tendencies represent the impacts of synoptic-or large-scale motion on temperature and humidity (Grabowski et al., 1996;Lee et al., 2018). The control run is performed in a threedimensional domain with horizontal and vertical extents of 300 and 20 km, respectively. ...
Using a modeling framework, this study investigates how a pyrocumulonimbus
(pyroCb) event influences water vapor concentrations and cirrus-cloud
properties near the tropopause, specifically focusing on how fire-produced
aerosols affect this role. Results from a case study show that when observed
fire intensity is high, there is an insignificant impact of fire-produced
aerosols on the development of the pyroCb and associated changes in water
vapor and cirrus clouds near the tropopause. However, as fire intensity
weakens, effects of those aerosols on microphysical variables and processes
such as droplet size and autoconversion increase. Due to this,
aerosol-induced invigoration of convection is significant for pyroCb with
weak-intensity fires and associated weak surface heat fluxes. This leads to
a situation where there is a greater aerosol effect on the transport of
water vapor to the upper troposphere and the production of cirrus clouds
with weak-intensity fires, whereas this effect is muted with
strong-intensity fires.
