The stratospheric polar vortex (SPV) weakening is linked to surface circulation changes.This study employs statistical analysis using reanalysis data to compare the anomalous SPV behaviour in the Northern (NH) and Southern (SH) hemispheres and its downward impacts on surface climate.The onset of annual SPV weakening occurs in mid-January and late S
Globally, there has been a remarkable growth in the number of underground constructions (UGC) such as railways, offices, hospitals and shopping malls.This expansion is a result of urban area extensions that are limited by the availability of buildable land.Underground construction can also be used to protect people from the Toy harshness of the out
