What are the primary meteorological factors that influence air pollution?

The meteorological parameters which have the most important influence on the diffusion of pollutants in the atmosphere are wind direction and speed, turbulence and stability.

What are the meteorological factors influencing the air pollution?

Air movements influence the fate of air pollutants.

When studying air quality, it is important to measure the following factors as they can help us understand the chemical reactions that occur in the atmosphere:

  • wind speed and direction.
  • temperature.
  • humidity.
  • rainfall.
  • solar radiation.

Which meteorological conditions and factors are responsible for severe air pollution episodes in an urban area?

A sudden stratospheric warming (SSW), weak East Asian winter monsoon, a weak Siberian High, weak meridional circulation, southerly wind anomalies in the lower troposphere, and abnormally weak surface winds and high humidity were responsible for the severe haze pollution events, rather than an abrupt increase in …

What are the primary sources of air pollution?

There are four main types of air pollution sources:

  • mobile sources – such as cars, buses, planes, trucks, and trains.
  • stationary sources – such as power plants, oil refineries, industrial facilities, and factories.
  • area sources – such as agricultural areas, cities, and wood burning fireplaces.

Which of these is one of the primary meteorological parameters?

Meteorological parameters (Wind speed, wind direction, temperature, and…

What are meteorological conditions?

Noun. 1. meteorological conditions – the prevailing environmental conditions as they influence the prediction of weather. environmental condition – the state of the environment.

What meteorological means?

1 : a science that deals with the atmosphere and its phenomena and especially with weather and weather forecasting studied the principles of meteorology. 2 : the atmospheric phenomena and weather of a region the meteorology of the Gulf of Mexico.

How meteorology affects air quality in a region?

Meteorological factors have significant impacts on the dilution and diffusion of air pollutants, and further affect the distribution and concentration of pollutants. For example, it was reported that the wind and rainfall could strongly affect the concentration of PM2.

What meteorological factors affect plume rise?

The meteorological parameters which influence plume rise are the horizontal wind speed (U) and stability, as de- noted by the vertical temperature or potential temperature gradient.

What are the 3 things that affect air quality?

The climate influences temperatures, cloudiness, humidity, the frequency and intensity of precipitation, and wind patterns, each of which can influence air quality.

What are five primary air pollutants?

5 Major Outdoor Air Pollutants

  • Ozone (O3)
  • Nitrogen Oxides (NOx)
  • Carbon Monoxide (CO)
  • Sulfur Dioxide (SO2)
  • Particulate Matter (PM10 and PM2.5)

What are primary and secondary air pollutants?

Primary & Secondary pollutant. Definition: A primary pollutant is an air pollutant emitted directly from a source. A secondary pollutant is not directly emitted as such, but forms when other pollutants (primary pollutants) react in the atmosphere.

What are the 5 major causes of air pollution?

We have listed 10 common air pollution causes along with the effects that have serious implication on your health on a daily basis.

  • The Burning of Fossil Fuels. …
  • Industrial Emission. …
  • Indoor Air Pollution. …
  • Wildfires. …
  • Microbial Decaying Process. …
  • Transportation. …
  • Open Burning of Garbage Waste. …
  • Construction and Demolition.

What role does topography play with local air quality?

On hill tops and exposed areas, moderate wind will typically cause the pollutant to be dispersed (blown and spread out) but in low-lying areas like valleys, it is harder for the wind to penetrate, causing air pollutants to become trapped and levels of air pollution to rise.

What are some factors that affect the relative humidity of the air?

Humidity depends on the temperature and pressure of the system of interest. The same amount of water vapor results in higher humidity in cool air than warm air. A related parameter is the dew point. The amount of water vapor needed to achieve saturation increases as the temperature increases.

Which of the following is the major photochemical smog?

Ozone is the most toxic constituent of photochemical smog, and it has caused considerable damage to agricultural and native plants in many locations.
