Polar Atmosphere Phenomena
: Focusing on the Polar Vortex
Mid-latitude Extreme Weather
2.Reinforce Cold Wave-Related Infrastructure
- Improve Power Grids
The Texas freeze, caused by a weakened polar vortex, led to a surge in electricity demand and widespread power outages due to frozen infrastructure. It is essential to improve power grids to prepare for such events.
- Preventive Measures
Implement plans for freeze prevention and emergency water supply.
- Enhance Transportation and Communication Infrastructure
Strengthen snow removal systems and prepare for potential communication network freezes to handle heavy snowfall and icy roads.
1.Strengthen Cold Wave Prediction Systems
- High-Resolution Forecasting Models
Utilize high-resolution numerical models to more accurately predict the possibility of extreme cold waves on a regional basis.
- Diverse Indicator Utilization
Enhance the reliability of predictions by using not only conventional indicators like polar vortex area, strength, and position, but also other metrics such as stratospheric temperature, wind speed, and jet stream variability.
