The relationships among CAW, heatwaves, wildfires, and pollution. Anomalous anticyclones characterize the atmospheric circulation that develops concomitantly over the three remote regions around the summertime Arctic (July and August). The authors named it the circum-Arctic wave (CAW) pattern. These anticyclones induce warm and dry conditions from the surface to the mid-troposphere. The CAW can drive heatwaves and wildfires; wildfire smoke also emits aerosols that increase PM2.5 in and around the Arctic

The past is often the window to our future, especially when it comes to natural disasters. Using data from the 2018 floods that struck southwestern Japan to calibrate a machine learning model, researchers from the International Research Institute of Disaster Science (IRIDeS) at Tohoku University and the Japan-Peru Center for Earthquake Engineering Research and Disaster Mitigation (CISMID, in Spanish), have successfully identified the flooding caused by Typhoon Hagibis.

Are density distributions of the vast universe and the nature of smallest particles related? In a recent research, scientists from HKUST and Harvard University revealed the connection between those two aspects, and argued that our universe could be used as a particle physics "collider" to study the high energy particle physics.
