Why is it sunny before the typhoon comes?

It was sunny before the typhoon came because of the tropical cyclone structure of the typhoon.

In tropical areas, there is usually a relatively calm stage before a typhoon approaches, and the weather at this stage is often sunny.

Typhoon is formed by the rising of warm and humid air. When it is formed and strengthened on the ocean, the surrounding air will be attracted to the center, and a lot of water and energy will be transported to the central cloud system from all directions. This process will lead to large-scale clouds and precipitation, forming the storm activity of the typhoon itself.

But before the typhoon approaches, its own strong storm activity can form a relatively stable environment. A strong downward airflow will restrain the development of rainfall and clouds and make the sky clear. In addition, the atmospheric circulation in this area will also be affected by typhoons, resulting in relatively calm weather conditions.

This sunny weather condition is usually a warning signal, which indicates that a typhoon is coming before strong winds and heavy rains come. Therefore, in the sunny days before the typhoon, people should be vigilant, pay close attention to the early warning information of meteorological departments, and take corresponding preventive measures to ensure personal and property safety.

Typhoon prevention measures:

1. Prepare for residents' safety: Before the typhoon comes, it is most important to ensure the safety of family members. Prepare enough food, drinking water, first-aid medicines and other daily necessities to deal with possible power outages and water cuts. Clean up the sundries around the house and fix outdoor furniture, flower pots, etc. To reduce the risk of being blown away by the wind. If you live in coastal areas or places prone to floods, you should know the location of shelters in advance and make evacuation plans.

2. Pay close attention to the weather forecast and emergency notice: pay close attention to the typhoon path and intensity information released by the meteorological department and keep abreast of the typhoon dynamics. Follow the emergency notices and instructions of the local government and relevant institutions, and follow the evacuation guidelines to ensure timely action. During the typhoon, avoid going out, especially near dangerous areas such as rivers and coastlines.

3. Strengthen the protection of buildings and houses: Strengthening buildings and houses is an important measure to reduce the damage and losses caused by typhoons. Check whether the roof, doors, windows and walls of the house are stable, and repair or reinforce possible problems such as water leakage and cracking. Before the arrival of the typhoon, the windows can be reinforced with protective plates or adhesive tapes to ensure that they can resist the typhoon's wind. In addition, waterproof measures can be taken in flood-prone areas, such as building flood levees and raising the ground height.
