Q: The increase in the orographic enhancement factor from cloud seeding does not fully compensate for the continuing decrease from air pollution. Cloud seeding for rain enhancement is aimed at accelerating the conversion of cloud droplets into precipitation particles, whereas air pollution has the opposite effect of suppressing the coalescence of cloud droplets into raindrops and the formation of ice hydrometeors. The Asian brown cloud is created by a range of airborne particles and pollutants from combustion (e.g., woodfires, cars, and factories), biomass burning and industrial processes with incomplete burning. The cloud is associated with the winter monsoon (November/December to April) during which there is no rain to wash pollutants from the air. Topographic cross section showing the effects of urban air pollution on precipitation as the clouds move from the California coast east to the Sierra Nevada Mountains. Maritime air (zone 1) is polluted over the coastal and Central Valley urban areas (zones 2, 3): no precipitation decrease occurs. The seeding effect might still persist there, but it is not associated with a decreasing trend of the unseeded conditions. It is apparent that the effects of cloud seeding and air pollution in the low-elevation areas are more limited because of the lack of an orographic enhancement to the rainfall. Air Pollution/Smog: This encompasses many greenhouse gases. Emissions from traffic and manufacturing plants form smog as UV radiation and heat cause the necessary chemical reactions to take place. As a result, the amounts of UV radiation reaching the surface is smaller under these conditions. Scientists call airborne particles of any sort — human-produced or natural — aerosols. The simplest effect of increasing aerosols is to increase clouds. To form clouds, airborne water vapor needs particles on which to condense. With more aerosols, there can be more or thicker clouds. In a warming world, that's good. Sunlight bounces off cloud tops into space without ever reaching Earth's surface, so we stay cooler under cloud cover. But that simplest effect doesn't always happen. If there's no water vapor in the air — the air is dry — aerosols can't make clouds. Different types of aerosols have different effects, and the same aerosol can have different effects depending on how much is in the air and how high it is. Soot particles at certain altitudes can cause cloud droplets to evaporate, leaving nothing but haze. They found that additional pollution over pristine regions of the ocean has a larger effect on the clouds than in already polluted regions. Essentially, adding the same amount of pollution to clean marine air makes clouds brighter and hold more water than when adding the same amount of extra pollution to dirty regions. Scientists at Pacific Northwest National Laboratory and the National Center for Atmospheric Research (NCAR) found that ocean-hugging clouds in clean regions are more affected by pollution than clouds in an already polluted setting. Cloud trails from ships, called ship tracks, are a small-scale example of this effect. Pollution exhaust from ships forms streaks of clouds that are brighter than neighboring clouds. The researchers learned that the amount of pollution already in a region strongly moderates any effect on cloud characteristics from additional pollution. Carbon dioxide is the major greenhouse gas produced by human consumption of fossil fuels, along with methane, nitrous oxide, and other carbon gases. Ship tracks, the long lines of clouds downwind of ships, provided a nice opportunity to study the effect of exhaust particles, called aerosols, on clouds. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys.

Q: The normal stresses of everyday life are unlikely to affect a pregnancy, but severe stress, like losing a job or going through a divorce, can increase the chances of premature labor. There’s even some research suggesting that very high levels of stress can affect the developing fetal brain. Street foods are the alternative food if you want to be a spend thrift. The taste of the food can be compared to the food being prepared at famous fast food and restaurants. The only difference is the price; it's more cheaper. Tourists, local and foreign, are also enjoying this kind of food setting. The harmful effects of fast food on our health can be of two forms; Short-term or long-term. The short-term effects may be such as lethargy, malaise, anxiety, etc. ” We consume without realizing chemical additives, GMOs in many countries vegetables (corn, soy …) and many other substances rejected by our body ”. Think about it the next time you are reaching for your second helping of cheesy nachos that accompanies the double stacked hamburger sandwich and large soda. Weight Gain. A negative effect of junk food on children is rapid weight gain, often leading to excessive weight and sometimes obesity. This is because it often tastes good, is not very filling and is high calorie. In addition, because of the competition among street vendors, some of them have to sell out-of-date food such as re-heated chicken wings. These factors can certainly have an effect on customers’ health. Sok Chhivsrun, 21, student (year 1 student at PUC) One big advantage of eating food from street stalls is that it’s cheap, so anyone can afford it. If we don't get the right information, our metabolic processes suffer and our health declines.If we get too much food, or food that gives our bodies the wrong instructions, we can become overweight, undernourished, and at risk for the development of diseases and conditions, such as arthritis, diabetes, and heart disease.In short, what we eat is central to our health. The effects of eating street food can vary depending on what is  eaten and who is eating it. Some street food can be high in  calories and cause weight gain. Some can be aci…dic and cause  heartburn. Street food can also be healthy and give a person  energy. There is, for example, the possibility of creating brand-new allergens. Despite the potential health implications, more GM foods appear each year. In 2011 the USDA approved the planting of genetically enhanced sugar beets (sucrose) and alfalfa (hay for livestock). Effects: The junk food contains a lot of oil and artificial flavoring and colors which stimulate the sebaceous glands to secrete more than normal sebum which causes acne. 6. Obesity: Reason: It has been found that people who have street foods and junk foods regularly are more prone to weight gain and obesity. Effects: Street food contains sugars, fats, salts etc. All these are very bad for the body in higher concentrations. Street food such as burgers, hot dogs and flavored popcorn have a  negative effect on school-going children. These foods are laden  with calories and saturated fats that con…tribute to obesity.

Q: This is called the heat of fusion. It takes additional heat to raise the temperature of the water to reach its boiling point. This is about 180 BTUs for 1 pound of water. To change the liquid state into water vapor, it requires an additional 972 BTUs per pound of water. By changing state twice; that is, ice to water to vapor, approximately 1,300 BTUs of heat energy per pound of water has been stored in the moisture which is bound to the air. Any time condensation and freezing occurs, that amount of heat energy will be released, thus raising the temperature of the air. Best Answer: Water vapor is the dominant greenhouse gas in the atmosphere. Water vapor high in the atmosphere can produce 'noctiluminescent' clouds, primarily from the space shuttle exhaust. At ground level it makes things humid and unpleasant, though it does prevent plant dessication. Dew and fog can be an important source of moisture in some environments. A broad question. Greenhouse gas. A greenhouse gas (abbrev. GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Changes in water vapor and clouds are amplifying global warming A new paper represents a major step in measuring and understanding the Earth’s climate John Abraham Overview of Greenhouse Gases. : 1  Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and wood products, and also as a result of certain chemical reactions (e.g., manufacture of cement). The increased water vapor in turn leads to an increase in the greenhouse effect and thus a further increase in temperature; the increase in temperature leads to still further increase in atmospheric water vapor; and the feedback cycle continues until equilibrium is reached. Water Vapor Confirmed As Major Player In Climate Change Date: November 18, 2008 Source: NASA/Goddard Space Flight Center Summary: Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change. Scientists will discuss the role of water vapor, the most abundant greenhouse gas, at a conference sponsored by the American Geophysical Union in Potomac, Maryland, October 12-15. Despite the fact that the water vapour concentration of the atmosphere is 5 times that of CO2 (around 0.3% by mass for water vapour cf around 0.06% by mass for CO2), the contribution of CO2 to the greenhouse effect is at least 10% (and more like 25-30% with the water vapour feedback). Magma contains dissolved gases, which provide the driving force that causes most volcanic eruptions. As magma rises towards the surface and pressure decreases, gases are released from the liquid portion of the magma (melt) and continue to travel upward and are eventually released into the atmosphere.
