Moisture transport by Atlantic tropical cyclones onto the North American continent [PDF]

, 2016
Tropical Cyclones (TCs) are an important source of freshwater for the North American continent. Many studies have tried to estimate this contribution by identifying TC-induced precipitation events, but few have explicitly diagnosed the moisture fluxes ...

Long-term persistency of a strong non-dipole field in the South Atlantic

Nature Communications
Earth’s magnetic field exhibits a dominant dipole morphology. Notwithstanding, significant deviations from the dipole are evident today, particularly the South Atlantic Anomaly (SAA), characterized by anomalously low-field intensity and high directional ...
