1. Abstract
What is in this post?
Lots of graphs with big pictures on PM2.5 and wind patterns in Hanoi and Ho Chi Minh City from 2016-2019
Only analyzing correlation weather parameters to the transport stage of PM2.5 in which wind and precipitation drive the process
Correlation of wind speed and precipitation rate to the observed PM2.5 concentration
A closer look on change of wind speed or change of PM2.5 and association of such in Hanoi
What this post cannot provide?
Causation between PM2.5 to weather patterns or any mathematical-derived relations
Any comprehensive conceptualization of mass-balance on PM2.5
Critical questions such as source, solution for PM2.5 conundrum
