Amazing Clouds You Have To See To Believe (Explained With Science)

Amazing Clouds You Have To See To Believe (Explained With Science)

Clouds are so amazing. Every day, the world is host to a million spectacles that would make even the most skilled artists throw away their brushes. It’s almost as though the planet lets its breath go on a cold day. These moisture formations hang in the air, sometimes daintily and sometimes threateningly.

While everyone has seen common types like stratus and cirrus, there exist cloud formations that I bet you’ve never even dreamed of!

    Also known as Nacreous clouds, from the French “nacre” (meaning Mother of Pearl), these clouds boast not just a fantastic shape and size, but also washes of color that paint across the sky like brush strokes. However, with their beauty also comes thorns. Nacreous clouds are formed in the stratosphere of the Polar extremes. Due to their altitude, they receive light from the sun even after it has  descended far beyond the horizon. They form far up enough that their crystalline shape allows chlorine to react rather than stay in its normally-inert form, which isolates chemicals that normally defend the ozone from destruction. In essence, these clouds are anti-sunblock for the planet.

      Interestingly, these clouds have only been documented after 1883’s eruption of the volcano Krakatau. They can only be observed a few minutes between day and night, when it’s just too dark to see properly. Theories as to why these clouds exist come from the fact that the eruption sent ash 80 kilometers into the sky. This fine ash allowed the formation of moisture particles around it. Now, without the ash in the sky, these clouds still exist, possibly because of the pollution from industrial plants. They are the highest known clouds in Earth’s atmosphere. They require dust or other microparticles, water vapour, and incredible cold temperatures in order to form.

        Officially called a Circumhorizontal Arc, these formations are not actual fire but definitely are rainbow-like, in a technical sense. This phenomenon is observable when plate-shaped ice crystals suspended in the atmosphere, either in cloud form or free-floating, are hit by sunlight at just the right angle, and refract like a prism. While technically not a cloud themselves, they can take place in clouds, like the recent ones captured in South Carolina.

          A cursory glance at these clouds will have you expecting the giant sky jellyfish invasion any second. It is because of their strange appearance that they are colloquially called Jellyfish Clouds. These clouds are formed when two layers of very dry air sandwich a layer of moist air. Basically, warm air rises through the moist layer, forming water vapor particles. Those particles gain enough mass to be too heavy to continue rising, and plunge back down toward the moist air layer, where they gather more of the water from that layer and fall as rain. However, the dry air below the moist layer causes the rain to evaporate before it hits the ground, creating the tentacle-like rain-cloud formation under the pillowy body formation.

          How to Live Longer? 21 Ways to Live a Long Life

          How to Live Longer? 21 Ways to Live a Long Life

          When it comes to living long, genes aren’t everything. Research has revealed a number of simple lifestyle changes you can make that could help to extend your life, and some of them may surprise you.

          So, how to live longer? Here are 21 ways to help you live a long life

          1. Exercise

          It’s no secret that physical activity is good for you. Exercise helps you maintain a healthy body weight and lowers your blood pressure, both of which contribute to heart health and a reduced risk of heart disease–the top worldwide cause of death.

          2. Drink in Moderation

          I know you’re probably picturing a glass of red wine right now, but recent research suggests that indulging in one to three glasses of any type of alcohol every day may help to increase longevity.[1] Studies have found that heavy drinkers as well as abstainers seem to have a higher risk of early mortality than moderate drinkers.

          3. Reduce Stress in Your Life

          Stress causes your body to release a hormone called cortisol. At high levels, this hormone can increase blood pressure and cause storage of abdominal fat, both of which can lead to an increased risk of heart disease.

          4. Watch Less Television

          A 2008 study found that people who watch six hours of television per day will likely die an average of 4.8 years earlier than those who don’t.[2] It also found that, after the age of 25, every hour of television watched decreases life expectancy by 22 minutes.

          Advertising

          Television promotes inactivity and disengagement from the world, both of which can shorten your lifespan.

          5. Eat Less Red Meat

          Red meat consumption is linked to an increased risk of heart disease and cancer.[3] Swapping out your steaks for healthy proteins, like fish, may help to increase longevity.

          If you can’t stand the idea of a steak-free life, reducing your consumption to less than two to three servings a week can still incur health benefits.

          6. Don’t Smoke

          This isn’t exactly a revelation. As you probably well know, smoking significantly increases your risk of cancer.

          7. Socialize

          Studies suggest that having social relationships promotes longevity.[4] Although scientists are unsure of the reasons behind this, they speculate that socializing leads to increased self esteem as well as peer pressure to maintain health.

          8. Eat Foods Rich in Omega-3 Fatty Acids

          Omega-3 fatty acids decrease the risk of heart disease[5] and perhaps even Alzheimer’s disease.[6] Salmon and walnuts are two of the best sources of Omega-3s.

          9. Be Optimistic

          Studies suggest that optimists are at a lower risk for heart disease and, generally, live longer than pessimists.[7] Researchers speculate that optimists have a healthier approach to life in general–exercising more, socializing, and actively seeking out medical advice. Thus, their risk of early mortality is lower.

          10. Own a Pet

          Having a furry-friend leads to decreased stress, increased immunity, and a lessened risk of heart disease.[8] Depending on the type of pet, they can also motivate you to be more active.

          11. Drink Coffee

          Studies have found a link between coffee consumption and longer life.[9] Although the reasons for this aren’t entirely clear, coffee’s high levels of antioxidants may play a role. Remember, though, drowning your cup of joe in sugar and whipped cream could counter whatever health benefits it may hold.

          12. Eat Less

          Japan has the longest average lifespan in the world, and the longest lived of the Japanese–the natives of the Ryukyu Islands–stop eating when they’re 80% full. Limiting your calorie intake means lower overall stress on the body.

          13. Meditate

          Meditation leads to stress reduction and lowered blood pressure.[10] Research suggests that it could also increase the activity of an enzyme associated with longevity.[11]

          Taking as little as 15 minutes a day to find your zen can have significant health benefits, and may even extend your life.

          14. Maintain a Healthy Weight

          Being overweight puts stress on your cardiovascular system, increasing your risk of heart disease.[12] It may also increase the risk of cancer.[13] Maintaining a healthy weight is important for heart health and living a long and healthy life.

          15. Laugh Often

          Laughter reduces the levels of stress hormones, like cortisol, in your body. High levels of these hormones can weaken your immune system.

          16. Don’t Spend Too Much Time in the Sun

          Too much time in the sun can lead to an increased risk of skin cancer. However, sun exposure is an excellent way to increase levels of vitamin D, so soaking up a few rays–perhaps for around 15 minutes a day–can be healthy. The key is moderation.

          17. Cook Your Own Food

          When you eat at restaurants, you surrender control over your diet. Even salads tend to have a large number of additives, from sugar to saturated fats. Eating at home will enable you to monitor your food intake and ensure a healthy diet.

          18. Eat Mushrooms

          Mushrooms are a central ingredient in Dr. Joel Fuhrman’s GOMBS disease fighting diet. They boost the immune system and may even reduce the risk of cancer.[14]

          19. Floss

          Flossing helps to stave off gum disease, which is linked to an increased risk of cancer.[15]

          20. Eat Foods Rich in Antioxidants

          Antioxidants fight against the harmful effects of free-radicals, toxins which can cause cell damage and an increased risk of disease when they accumulate in the body. Berries, green tea and broccoli are three excellent sources of antioxidants.

          21. Have Sex

          Getting down and dirty two to three times a week can have significant health benefits. Sex burns calories, decreases stress, improves sleep, and may even protect against heart disease.[16] It’s an easy and effective way to get exercise–so love long and prosper!
