A large amount of heat flux from aerodynamic heating acts on reusable spacecraft; thus, an accurate heat flux prediction around spacecraft reentry is essential for developing a high-performance reusable spacecraft. Although the approximate convective-hea...

The southward propagation of cold-air frontal boundaries into the Gulf of Mexico region initiates a cascade of coupled air?sea processes that manifests along the coastlines as an apparent brightness anomaly in the ocean color signals. Our hypothesis is t...

The eccentric dipole (ED) is the next approach of the geomagnetic field after the generally used geocentric dipole. Here, we analyzed the evolution of the ED during extreme events, such as the Matuyama-Brunhes polarity transition (~780 ka), the Laschamp ...
