Lessons from Texas Freeze: 5 Ways to Strengthen US Energy Resilience


Even as people are suffering through the harshest winter storm Texas has seen in decades, the reasons for the state’s devastating power grid failure have become a political battleground. While vulnerable people freeze in their homes, pundits snipe about whether wind turbines are to blame. Tiếp tục đọc “Lessons from Texas Freeze: 5 Ways to Strengthen US Energy Resilience”

Typhoon Mangkhut: Philippines braces for one of the strongest in its history


Five million could be hit by super storm as gusts of up to 255km/h are expected

Philippines is braced for one of the strongest typhoons in its history, as authorities evacuate families in their thousands, close schools and put rescuers and troops on full alert in the country’s north.

Five million people are expected to be affected by Typhoon Mangkhut, which experts have categorised as a super typhoon with powerful winds and gusts equivalent to a category-5 Atlantic hurricane.

By Friday morning, almost 10,000 people across three regions had been evacuated and 22 domestic flights cancelled. By the evening, strong winds had already downed trees in Tuguegarao, a city in the main northern island of Luzon, where almost all businesses had been shuttered and police were patrolling otherwise quiet streets.

World Lightning Map: Lightning is not uniformly distributed across the Earth.

world lightning map

lightning flash scale

World Lightning Map: The map above shows the average yearly counts of lightning flashes per square kilometer based on data collected by NASA’s Lightning Imaging Sensor on the Tropical Rainfall Measuring Mission satellite between 1995 and 2002. Places where less than one flash occurred (on average) each year are gray or light purple. The places with the largest number of lightning strikes are deep red, grading to black. Enlarge.

What is Lightning?

Lightning is a sudden high-voltage discharge of electricity that occurs within a cloud, between clouds, or between a cloud and the ground. Globally, there are about 40 to 50 flashes of lightning every second, or nearly 1.4 billion flashes per year. These electrical discharges are powerful and deadly.

Thunderstorm activity and research on lightning position in Vietnam


Vietnam is situated in the centre of the Asian thunderstorm region – one of three thunderstorm centres in the world. This article gives an overview of thunderstorm activity in Vietnam and results from the research on lightning position over the past year in Institute of Geophysics under the Vietnam Academy of Science and Technology.

Research on thunderstorms aims to observe and study thunderstorm activity over space and time, as well as exploring how and why lightning formulates. Research on lightning position aims to define the density of lightning (number of lightning flash/km2 /year), and also measure other lightning parameters such as the intensity and the slope of the lightning bolt. Lightning density is an important specific quantity for thunderstorm activity in each region. It requires complicated steps to determine a lightning bolts density. This value is different according to region, depending on characteristics in climate terrain and other weather conditions.

Save the children

Disaster-prone Vietnam is susceptible to rapid-onset emergencies like storms, typhoons, and flooding annually. During these times, children are unable to go to school due to unsafe conditions and parents fearing for their children’s safety. Approximately 70% of the population is living in coastal and low-lying areas, resulting in high vulnerability to extreme weather events intensified by climate change and global warming.

As part of Save the Children in Vietnam’s risk reduction work, the country office has been working to improve the way hazard risk information is shared. Partnering with local government agencies and mobile companies, Save the Children initiated an SMS disaster early warning system that provides weather information to the vulnerable coastal provinces of Thua Thien Hue, Quang Nam, and Da Nang.

Viet Nam News HCM CITY — The HCM City People’s Committee has asked city departments and all 24 districts to prepare for natural disasters this year by completing maps about flooding hotspots and raising public awareness about disaster risks.

The maps will show the flood-prone locations that are often inundated with water caused by strong storms. Tiếp tục đọc “HCM City prepares for natural disaster prevention”
