- Smog: Car exhaust and industrial emissions are the greatest cause of smog, so it’s really only prevalent in highly populated cities. Smog can cause long-term health problems, especially for individuals with sensitivities or a weakened immune system.
- Greenhouse effect: This is one of the most talked-about air pollution effects. It’s caused by a buildup of carbon dioxide produced by burning fuel. It traps heat closer to the Earth, causing temperatures to rise and ultimately leads to climate change. This gradual warming trend causes oceans to rise as icecaps melt, and can cause shifts in weather patterns that create more hurricanes and other natural disasters.
- Acid rain: While acid rain can be caused by volcanic emissions, it is more commonly associated with rain that has mixed with gaseous industrial pollution, creating acidic compounds that fall back to Earth as acid rain. This harmful pollution affects both plants and animals.
- Warm conditions: A high pressure center in the mid and upper-levels of the atmosphere tends to produce warm, clear conditions.
- Cold conditions: A high pressure center in the lower levels of the atmosphere and at the surface in the winter usually brings cold temperatures, but not stormy conditions.
- Clear skies: The column of air within a high pressure zone moves downward, which makes it difficult for clouds to grow. This tends to clear the clouds from the sky creating this type of weather associated with high pressure.
- Dry air: Sinking air within a high pressure zone tends to warm up and dry out, thus decreasing the chances of precipitation.
- Slow, clockwise winds: The Coriolis effect is responsible for this weather associated with high pressure. (In the Southern Hemisphere, high pressure zones create slow, counterclockwise winds.)
- Reduced air quality: Since wind speeds tend to drop in high pressure zones, pollution can build up. Higher temperatures allow for chemical reactions in the air to take place. Plus, the lack of clouds and warmer weather make the perfect conditions for smog or ground-level ozone.
- Clear conditions followed by stormy weather: An abrupt fall in pressure may indicate that the nice weather associated with a high pressure zone will leave as quickly as it came, since a stormy low pressure zone may be following close behind.
- Clear conditions lasting for days: A gradual rise in pressure usually indicates that nice weather can be expected for the next several days.
- Atmospheric pressure steadily decreases and temperatures remain moderate.
- Winds blow from the northeast, east, and finally southeast in the Northern Hemisphere.
- Precipitation may occur in the form of drizzle, rain, freezing rain, sleet, or snow.
- Stratus and nimbus clouds may cover the sky.
- The dew point rises steadily.
- Atmospheric pressure begins to level off.
- Temperatures begin to rise and humidity increases.
- Winds tend to shift to the southeast.
- Precipitation dies off to a mere drizzle.
- Stratus clouds dominate the sky.
- The dew point remains steady.
- Atmospheric pressure begins falling again.
- Temperatures are higher than before the front hit, and then tend to level off.
- Winds blow south or southwest in the Northern Hemisphere (north or northwest in the Southern Hemisphere).
- Cloudy conditions begin to clear.
- The dew point rises and levels off.
- Climate change
- Changes in ocean temperature
- Jet stream variances
- Formation of large high pressure zones aloft
- Economically: With losses in the timber, agriculture, and fishing industries, consumers often suffer from higher prices or have difficulty finding certain products.
- Socially: When droughts become severe, conflict can arise over who should control the fertile land, water resources, and scarce commodities. Droughts can even cause the loss of homelands, require lifestyle changes, and lead to increased health risks.
- Environmentally: Water sustains all life, and during a drought, biodiversity may suffer, migrations may change, air quality can reduce, and soil can erode.

- A total solar eclipse usually lasts less than 5 minutes, but some previous eclipses have lasted up to 7.5 minutes.
- The impressive appearance of a total solar eclipse can be seen only within a 167-mile-wide strip of Earth.
- Everyone within a 3,000 mile radius of the total eclipse can still enjoy a partial eclipse.
- During a solar eclipse, some animals and birds behave perplexedly, not knowing whether the time has already come to sleep or not.
- There are at least two (2) solar eclipses (partial, annular, or total) visible from somewhere on Earth every year, but there are never more than five (5) in a single year.
- Anyone at the North Pole or South Pole will be able to see only a partial solar eclipse.
- During a total solar eclipse, the horizon appears to glow. What you’re seeing is a distant location that’s not in the shadow of the moon, or direct umbra.
- You might need a jacket during a total eclipse because the temperature can drop about 20 degrees or more as totality approaches.
- If a total eclipse occurred over your hometown recently, you can rest assured it will happen again. In fact, nearly identical eclipses visible from a particular location on Earth occur every 54 years and 33 days.
- Thanks to the study of ancient accounts recording solar eclipses, modern astronomers have determined that the Earth’s rotation is slowing by 0.001 second per century.

- Pressure equals 30 inches: When there is no change in pressure, the weather is usually stable with no major changes expected.
- Pressure is greater than 30 inches: Pressure increases indicate that the air is “heavier,” which can be a reflection of cooler, much drier conditions moving in, or that the air is sinking, which tends to clear out any clouds and lessens the chance for precipitation.
- Pressure is lower than 30 inches: Pressure decreases indicate that the air is “lighter” which can be a reflection of warmer, more humid conditions moving in, or that the air is rising, which can lead to cloud and/ or storm formation. Low barometric pressure often means windy conditions are on the horizon.
