IMD issues orange alert for heavy rain, Telangana, Andhra govts

• The low-pressure area, formed over northwest Bay of Bengal on Thursday, is currently active over north coastal Odisha. It is expected to become more organised and move northwestwards, over West Bengal on Sunday (Aug 10th, 2020) Chhattisgarh on Monday and Madhya Pradesh on Tuesday morning. As per IMD (India Meteorological Dept.), the system will bring fairly widespread to widespread rain with isolated heavy rain and thunderstorm over eastern India over the next three days.
• As per the forecasts, Telangana is likely to witness isolated very heavy rains on Friday and Saturday and isolated extremely heavy rainfall on Sunday. The India Meteorological Department (IMD) has also forecast widespread rainfall with isolated heavy to very heavy falls over Odisha, coastal Andhra Pradesh and Telangana over the next 2-3 days.The weather department has issued an orange alert for several districts of Telangana that is already receiving extremely heavy rainfall. As both Telangana and Andhra Pradesh receive heavy rainfall, chief ministers of the two states held high-level meetings to assess the situation.Heavy rains have battered both Andhra Pradesh and Telangana over the past weeks.

Air Pollution Meteorology

• Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people’s nerves, brain, kidneys, liver, and other organs. Air pollution is a mixture of solid particles and gases in the air. When ozone forms air pollution, it’s also called smog.
• Some air Major Outdoor Air Pollutants : Ozone (O3),Nitrogen Oxides (NOx),Carbon Monoxide (CO),Sulfur Dioxide (SO2),Particulate Matter pollutants are poisonous. Inhaling them can increase the chance you’ll have health problems.
• Causes of Air Pollution;- Almost all of the common air pollutants can be produced by industrial processes, Transportation Emissions, Agriculture Side-Effects, Home Heating, Home Cooking, Volcano Eruptions and Forest Fires.
• Meteorological factors have an important effect on the amount of pollution in the atmosphere. Temperature and solar radiation affect the quantities of pollutant emitted by their influence on the amount of space heating required. Sunshine is required in a photochemical production of oxidants forming smog. The wind velocity, turbulence and stability affect the transport, dilution and dispersion of the pollutants.  The humidity is a frequent and important factor in determining the effect that concentrations of pollutants have on property, vegetation and health. Meteorological processes that influence air quality – Sunlight – Horizontal dispersion Vertical mixing Global – Vertical mixing – Transport – Clouds – precipitation- Air Masses and Fronts.
