What do you know about Hurricane?
"Huracan", a Spanish word meaning "storm", is the originated word for HURRICANE. It basically refers to tropical cyclones coming from the Pacific, known as "Typhoon" which is a Greek word. Hurricane is a natural disaster that occur when the ocean waters surpass the threshold at 26 degrees Celsius or 79 degrees Fahrenheit. The excessive warm water causes evaporation that create humid air and clouds lead to a severe storm. The wind coming from the Earth will then add energy and forces in the air to steer it and grow. In a simple definition, Hurricane is a strong storm that causes severe winds waving from above the air.
Now, how does Hurricane form?
Several conditions have been confirmed by NOAA "National Oceanic and Atmospheric Administration"
Weather conditions
Hurricane is formed by severe weather condition when thunderstorms occur up in the air. Science explained that when the surface of the Earth gets warm, so does the air. The air will then rise above the atmosphere and transfers the heat coming from the Earth. When arriving into the atmosphere, the water vapor starts to cool down and release the heat to form clouds. When temperature is freezing, the clouds grow upward into the areas which cause Thunderstorm.
Ocean conditions
Hurricane starts with the warm water located near the equator and only form in the tropical regions which the temperature is at least 80F. Warm water under the ocean is the main causes of hurricane. However, depends on latitude and temperature of the water that the water vapor creates clouds and pressure up in the air. The latitude has to be higher than usual which is between 5 to 20 degree in order to form tropical oceans. When temperature of sea water heating up to 26 degree Celsius-/-09 the heats released in the atmosphere that lowers the pressure then causes wind at the ocean surface to spiral and pick up speed. This result to warm water is the condition of intense storm, called Rain bands . When the warm water continues to rise upward, the winds continue to blow in a circular pattern around a center of the sea water
Wind activity
Winds play role in forming hurricane because it cause more warm water to evaporate in the air. The moist of the air that rises up to the atmosphere begins to cool down and the condenses back to the surface of the ocean into droplets. These water droplets form a humongous clouds to accumulate storm and form the Eyewall. When the warm water continues to rise upward, the winds continue to blow in a circular pattern around a center of the sea water. The level of the winds speed to form hurricane should reaches 74mph, hurricane is officially formed.

Conditions from physical geography point of view
Coriolis Effect
As Coriolis force is the result of Earth rotation around its axis, this movement allow the air and water to curve to the right in the Northern Hemisphere then left in Southern hemisphere. Its motion is perpendicular in a clockwise direction. This information can be used to forecast the path of the waves or storms. The deflection of the wind that flows create a circulation around the center which makes the storm stronger.
Pressure gradient force
The higher pressure of the air in certain areas is moved by the pressure gradient force to lower pressure. Hurricane have an eye which the head of the storm with the most high speed is moving, which is the center. As the force is directed in a perpendicular way to the isobars, air from high pressure leads to lower pressure. The heats in the air allow molecules to move and become less dense, the air eventually will then goes to higher altitudes when the air molecules reduces its compression by gravity.
How human experience is shaped by global forces?
The intricate interplay of global forces, like climate change, profoundly influences human experiences. Scientific data confirms that the rise in sea surface temperatures due to climate change contributes to the intensification of hurricanes . However, this intensification reinforces the destructive power of hurricanes, leading to more severe effects on communities found in coastal regions worldwide. Communities in low-lying coastal areas are vulnerable and lack adequate resources, infrastructure, and support systems, bearing the disproportionate burden of intensified storms like Hurricanes. They are often marginalized due to systemic inequalities. Hence, the hurricane impacts highlight the need for fair policies and international cooperation to combat the negative effects of climate change as they reveal vulnerability to global forces.
Issues of Hurricane legacy from a global perspectives
Hurricanes cause immediate destruction to the impacted areas and highlight larger systemic weaknesses, highlighting the need for international collaboration in disaster management and climate resilience. Hurricanes have left a legacy that emphasizes how interdependent nations are and how everyone must take responsibility for decreasing their effects. Although some areas may experience the most damage from hurricanes, supply lines, migratory patterns, and economic stability are all affected globally . To successfully tackle the many issues that hurricanes present, international cooperation is vital, and it includes long-term investments in infrastructure resilience, climate adaptation, and sustainable development initiatives. It will serve as an addition to integrated procedures for preparing for and responding to disasters.
