The formation of Tropical cyclones

⭐Typhoon = tropical cyclones⭐

How are topical cyclones formed?

How is it formed?

  • Air is heated and rises when the ocean surface temperature reaches over 26° ^ (When hot air rises, air pressure drops)
  • -> Surrounding air is drawn in, replacing the rising air
  • -> creates strong convection and a low-pressure centre is gradually formed
  • water vapour in the rising air will cool and condense, -->forming clouds
  • Heat energy is released in the process —> more energy for the low-pressure system 
  • ^ Allowing it to strengthen the low-pressure system
  • A tropical cyclone is formed

. ݁₊ ⊹ . ݁˖ . ݁Vietnam is situated along the western Pacific Ocean, making it easier for typhoons to strike after it is formed in the ocean. ݁₊ ⊹ . ݁˖ . ݁


Tropical cyclones have 2 structures: the eye and rainbands

Effectiveness of the Measures

In response to Typhoon Haiyan, the Vietnamese government and various organizations took some measures to help cope with the storm and prevent further damage.

process of disaster management

The government used its disaster management agencies and military to conduct searches and rescue operations, provide emergency shelter, and distribute food, water and essential supplies to the affected communities. -> ensured that the basic needs of the affected victims were met in the aftermath of the typhoon.

These actions helped Vietnam victims recover faster from the devastating storm. It also saved many lives and prevented further loss of life during the height of the storm. 

The Red Cross

Other international humanitarian organisations, such as the Red Cross, also provided emergency relief assistance. 

Putting people's safety and well-being at the forefront of any disaster preparedness plan is essential.

To make sure everyone is safe, Prioritizing measures such as early warning systems, infrastructure resilience, and community preparedness can minimize the potential impact of natural disasters on their safety and security. 

Conclusion

  • Typhoon Haiyan has caused severe damage to the Philippines and Vietnam.
  • 4.1million people were made homeless, many schools were damaged
  • —>led to temporary suspension of education institutions.
  • 600,000 hectares of Farmland were affected, winds and flooding led to the destruction or damage of road and infrastructure in affected areas.
  • prioritizing measures such as early warning systems, infrastructure resilience, and community preparedness is essential
