In this study, the levels of meteorological parameters like maximum temperature (°F), relative minimum humidity (%), dew point wind speed (mph), rainfall (in), and air pressure (in) were analyzed for all three COVID-19 pandemic waves in NCT Delhi, India. After doing statistical analysis, results showed that only a few parameters, (maximum, minimum, relative), point, humidity, pressure, linked t...
