Evaluation of aerosol loading and its relationship with geopotential height in Nigeria’s Guinea Coast [PDF]

open access: goldBulletin of the National Research Centre
Climate variability and atmospheric changes significantly affect weather patterns and human activities. Aerosols impact the Earth's climate by influencing cloud formation, scattering radiation, and cooling the planet. However, aerosols, like black carbon,

A Cut-off low at 500 hPa Geopotential Height and Rainfall Events over Iraq: Case Studies

open access: goldIraqi Journal of Physics, 2022
A cut-off low is a closed low with a low value of geopotential height at the upper atmospheric levels that has been fully detached (cut-off) from the westerly flow and move independently. A cut-off low causes extreme rainfall events in the mid-latitudes

The Quasi-Biweekly Oscillation of Summer Rainfall in Southern China and Its Relationship With the Geopotential Height Anomaly Over the North Atlantic Ocean [PDF]

open access: goldFrontiers in Earth Science, 2021
Summer precipitation in East Asia has significant quasi-biweekly (10–30-day) oscillation characteristics. By using gauge-based precipitation and ERA-Interim reanalysis data, the basic mode of the quasi-biweekly oscillation of summer precipitation in East
