Explanation and Facts of Wind and a Hurricane as a Form of Hydrometeorological Disaster

Explanation and Facts  of Wind and a Hurricane as a Form of Hydrometeorological Disaster.

 Reporting from Weather and Climate (2018), the wind is moving air. The movement of the wind is caused by several things. One of them is because the earth rotates or rotates. Air also moves because of the difference in air pressure around it. The wind flow comes from a place with high air pressure to a place with low air pressure. 
    The occurrence of the wind is influenced by the rotation of the earth along with the heating of an area by the sun. There are several properties of the wind: 

1. The wind has a very different wind speed from one place to another, and from time to time. 

2. Wind has properties that can cause pressure on a surface that opposes the direction of the wind. 

3. Wind also has the property of accelerating the cooling of a hot object. 

     Wind is invisible to the eye Due to the small number of particles, there is no reflected light. So in the absence of light, nothing can be reflected into the air into your eyes. 

There are several types of wind, here's an explanation. 

1. Land breeze and sea breeze 
     Land breezes and sea breezes occur due to differences in the nature of land and sea in absorbing and releasing solar thermal energy. The existence of a land breeze occurs because the heat energy absorbed by the earth's surface throughout the day will be released more quickly by the land. Meanwhile, in the ocean, heat energy is in the process of being released into the air. 

2. Mountain Wind and Valley Wind 
    Valley breezes occur when the sun rises. The top of the mountain is the area that gets heat first and during the process, the slopes of the mountain get more heat energy than the valleys. This condition causes a temperature difference between the two. Hot air from the mountain slopes rises and is replaced by cold air from the valley. As a result there is a flow of air from the valley to the mountain. 

3. Hurricane/Whirlwind 
    A hurricane/whirlwind is also known as a cyclone, which is a strong wind that comes suddenly, has a center, moves in a spiral like a spiral to touch the earth's surface and disappears in a short time (3-5 minutes). The average wind speed ranges from 30-40 knots. This wind comes from Cumulonimbus (Cb) clouds, which are dark gray and towering clumpy clouds. 

4. Monsoon Wind 
  Monsoon winds are winds that blow periodically (at least three months) and the pattern will be opposite from one period to another. 

     Well, how about the fact that a tornado occurs, it is known that tornadoes can cause severe damage if they occur in densely populated settlements. Tornado wind speeds can reach 40 to 50 km/hour. This wind touches the earth's surface and will disappear after 3 to 5 minutes.
    Usually, a hurricane forms some time after there are signs of dark skies, black thunderstorm clouds, and the sudden appearance of a funnel from the clouds. What Causes Tornadoes? Tornados occur because of the difference in air pressure so that the air pressure forms a vortex in the weather system. 
   There are 3 stages of hurricane formation, namely,

1. the growing phase
    The growing phase is characterized by the presence of air currents that rise upwards with strong pressure, in the clouds. At this stage, the water droplets and crystals cannot yet become rain because they are still being held back by rising air currents.
2. The adult phase 
    The adult phase, rain begins to fall and causes friction between rising and falling air currents. When the air currents rise and fall, they create a shear current that rotates and forms a vortex. The longer, the air currents will be faster and form a cyclone that touches the earth's surface.
3. The extinct phase.  
   Furthermore, in a whirlwind occurred. Then in the final phase, namely the extinction phase, the air mass will expand throughout the cloud, then stop, and the hurricane can end. 

    Well, that's an explanation of a Hurricane as a form of hydrometeorological disaster.

  So what happens if we accidentally swallow gum? Related to this, many are curious what the impact can be felt if we swallow it. Registered dietitian Beth Czerwony explains what actually happens when swallowed gum goes into the stomach. According to him, occasionally swallowing gum is harmless, but don't get used to it. Most chewing gum on the market is made from a gum base which is a synthetic material, not a real food ingredient. This gum base does not provide any nutritional value, and is indigestible. That means, our bodies can't break down chewing gum like food.

Do mosquitoes Prefer O type Blood?

Do mosquitoes Prefer O type Blood?  
     Itching and bumps due to mosquito bites are often uncomfortable, especially during sleep. Have you ever felt like you were being chased by mosquitoes more than anyone else around? It turns out that there is a reason why the body is favored by mosquitoes. 
    To find out the cause, see the following review. it turns out that mosquitoes like someone in a certain way. One of the factors that make some people attractive to mosquitoes is blood type.   
   People with different blood types have different sets of specific proteins (antigens) on the surface of their red blood cells. A person inherits blood type from his parents. Basically everyone has a different blood type. The difference in this type of group is based on the presence or absence of antigens in red blood cells and blood plasma. 
     Antigens are grouped into eight basic blood types, namely A, B, AB, and O, each of which can have positive or negative variations (rhesus). 
     The following are characteristics of blood groups: 
A: has only A antigens on red blood cells (and B antibodies in plasma) 
B: has only B antigens on red blood cells (and A antibodies in plasma) 
AB: has A and B antigens on red blood cells (but neither A nor B antibodies in plasma) 
O: does not have A and B antigens on red blood cells (but has A and B antibodies in plasma) 
     Well, what about someone with type O blood, mosquitoes prefer? this is the reality. The fact is that a study was conducted in 1974 by recruiting 102 participants to look at the various individual factors that attract mosquitoes. 
     When the researchers analyzed the results, they found that mosquitoes were more likely to bite people with blood type O.
   Another study in 2004 examined mosquito preferences for blood type as well as secretor status. The overall results found that: More mosquitoes landed on people with blood type O. 
    Mosquitoes identify this by the chemical signals released in the body, especially body odor. Yep! Mosquitoes (especially females) consume blood because they need serum protein contained in the blood to support their eggs. At least based on the senses of mosquitoes, the best type of protein with the highest levels is found in blood type O organs.

Here are Facts about Saliva

 
Facts about Saliva  

      Saliva is a fluid that plays an important role in supporting oral health and the digestive process of food. If the amount of saliva is too little or too much, this could be a sign of oral health problems or overall body health. Saliva is produced by the salivary glands located in the mouth. 
     These glands produce approximately 1-2 liters of saliva each day. Saliva contains protein, minerals, water, and the enzyme amylase which functions to digest carbohydrates.

        These are some Facts about Saliva: 

1. In a year we can produce 2 saliva bathtubs. Saliva production varies from person to person But on average each person will produce 0.7 liters of saliva per day. That is enough to fill 2 medium sized bathtubs in a year!

2. Saliva protects teeth and gums Saliva serves to lubricate our mouths and is crucial for oral health. Saliva also helps kill bacteria, fight infection, and tooth decay. 

3. Helps the process of breaking down food The main composition of saliva is water, and this is the key in the process of digestion of food. Water in saliva can make food softer and easier to swallow. Without saliva, it is impossible for us to digest food because food will not be completely broken down. 

4. Detect taste When we eat, the molecules in the food will dissolve in the saliva. Every food that enters the mouth will bring its own taste and we need saliva to detect the taste of the food. 

5. Heal wounds in the mouth faster Because of saliva, wounds in the mouth will heal faster than wounds elsewhere. This is because the fluid creates a moist environment in our mouth, and helps the cells we need to heal wounds. Saliva also contains proteins that our bodies use for the healing process. 

6. Saliva production will decrease when we are afraid or nervous It is very common that we will feel our mouth become dry when we feel restless or nervous. The flow of saliva is controlled by the nervous system, and that is what causes saliva production to decrease in the "fight or flight" response. 

7. Detect disease Saliva samples can be used as a tool to diagnose disease in a person. Having a constantly dry mouth, can be an indication of some serious health problem or disease. Only by analyzing certain proteins in saliva, doctors are able to assess the risk of heart disease, and even other diseases. 

8. Glandular stones We can also experience glandular stone disease, you know! This is similar to kidney stones. Saliva is formed in the salivary glands, then flows into our mouths. Sometimes, the chemicals in saliva can crystallize to form small stones and can block saliva from entering the mouth. 

9. Saliva contains natural pain killers The compound, called opiorphin, was discovered in 2006 and is estimated to be a painkiller up to six times stronger than morphine. According to a paper published on the findings, opiorphins appear to be inhibitors of pain perception. 

10. Chewing gum is good for dental health But make sure the gum you chew doesn't contain sugar. By chewing gum, saliva production will increase and it is good for our dental health.
