Concurrent increases in winter precipitation and summer wildfire risk in a warming Alaska
Alaska is experiencing simultaneous trends of increased winter wetness and heightened summer fire risk due to global warming, leading to more frequent wildfires and greater unpredictability in fire behavior in recent decades. Large-ensemble simulations show that warming drives distinct seasonal changes: in winter, an intensified ridge over the western U.S. enhances moisture transport to Alaska, increasing precipitation while promoting vegetation …
Statistical seasonal prediction of Arctic sea ice concentration based on spatiotemporal anomaly persistent method
Accurate prediction of Arctic sea ice is crucial for high-latitude and even mid-latitude climate prediction. It significantly affects atmospheric circulation, the environment, ecology, and maritime transport. This study developed a statistical prediction model to predict monthly Arctic sea ice concentration for up to one year based on the season-reliant empirical orthogonal functions (SEOFs) technique. Its prediction skill was compared with that …
Improving the seasonal forecast by utilizing the observed relationship between the Arctic Oscillation and Northern Hemisphere surface air temperature
Although the seasonal prediction skill of climate models has improved significantly in recent decades, the prediction skill of the Arctic Oscillation (AO), the dominant climate mode over the Northern Hemisphere, remains poor. Additionally, the local representation of AO impacts has diverged from observations, which limits seasonal prediction skill of climate models. In this study, we attempted to improve prediction skill of surface air temperatur…
Precipitation-induced abrupt decrease of Siberian wildfire in summer 2022 under continued warming
Wildfires in Northeast (NE) Siberia have become more frequent owing to the warming climate, exerting a profound impact on the global carbon cycle. While an increase in global temperature is recognized as a primary driver of unprecedented wildfires, the role of precipitation during wildfire season is relatively unexplored. Here, we present evidence that an increase in summer precipitation led to a sudden decrease in NE Siberian wildfires, especial…
Dynamical-statistical method for seasonal forecasting of wintertime PM10 concentration in South Korea using multi-model ensemble climate forecasts
Climate conditions and emissions are among the primary influences on seasonal variations in air quality. Consequently, skillful climate forecasts can greatly enhance the predictability of air quality seasonal forecasts. In this study, we propose a dynamical-statistical method for seasonal forecasting of particulate matter (PM 10 ) concentrations in South Korea in winter using climate forecasts from the Asian Pacific Climate Center (APCC) multi-mo…
Changes in fire weather climatology under 1.5 °C and 2.0 °C warming
The 2015 Paris Agreement led to a number of studies that assessed the impact of the 1.5 °C and 2.0 °C increases in global temperature over preindustrial levels. However, those assessments have not actively investigated the impact of these levels of warming on fire weather. In view of a recent series of high-profile wildfire events worldwide, we access fire weather sensitivity based on a set of multi-model large ensemble climate simulations for th…
Recurrent pattern of extreme fire weather in California
Historical wildfire events in California have shown a tendency to occur every five to seven years with a rapidly increasing tendency in recent decades. This oscillation is evident in multiple historical climate records, some more than a century long, and appears to be continuing. Analysis shows that this 5–7 year oscillation is linked to a sequence of anomalous large-scale climate patterns with an eastward propagation in both the ocean and atmosp…
Impacts of the Arctic-midlatitude teleconnection on wintertime seasonal climate forecasts
The impact of the Arctic on midlatitude weather and climate is still in scientific debate. The observation-based analysis, however, shows frequent concurrences of Arctic warming with extreme cold in the midlatitudes, and vice versa. This teleconnection could aid in seasonal climate forecasts for the midlatitudes. This study assessed the forecast skill of Arctic temperature and the Arctic-midlatitude teleconnection patterns in operational seasonal…
Intensification of the East Asian summer monsoon lifecycle based on observation and CMIP6
Long-term changes in the East Asian summer monsoon (EASM) lifecycle since 1979 are analyzed based on observational datasets and historical simulations of the Coupled Model Intercomparison Project Phase 6 (CMIP6). According to the observation, the active and break phases of EASM have intensified resulting in a shorter but stronger rainy season, followed by a longer dry spell. This intensification in the active-phase precipitation is accompanied by…
How does the SST variability over the western North Atlantic Ocean control Arctic warming over the Barents–Kara Seas
Arctic warming over the BarentsKara Seas and its impacts on the mid-latitude circulations have been widely discussed. However, the specific mechanism that brings the warming still remains unclear. In this study, a possible cause of the regional Arctic warming over the BarentsKara Seas during early winter (OctoberDecember) is suggested. We found that warmer sea surface temperature anomalies over the western North Atlantic Ocean (WNAO) modulate the…
Intensified Arctic warming under greenhouse warming by vegetation–atmosphere–sea ice interaction
Observations and modeling studies indicate that enhanced vegetation activities over highlatitudes under an elevated CO2 concentration accelerate surface warming by reducing thesurface albedo. In this study, we suggest that vegetation-atmosphere-sea ice interactions overhigh latitudes can induce an additional amplification of Arctic warming. Our hypothesis is testedby a series of coupled vegetation-climate model simulations under 2xCO2 environment…
Improvement in simulation of Eurasian winter climate variability with a realistic Arctic sea ice condition in an atmospheric GCM
The present study investigates how much a realistic Arctic sea ice condition can contribute to improve simulation of the winter climate variation over the Eurasia region. Model experiments are set up using different sea ice boundary conditions over the past 24 years (i.e., 1988-2011). One is an atmospheric model inter-comparison (AMIP) type of run forced with observed sea-surface temperature (SST), sea ice, and greenhouse gases (referred to as Ex…
