Causes of typhoon formation

The first typhoon "Wasp" in the Pacific started this year's hurricane model, but the hurricane season has not officially started, usually until June, but dangerous weather systems have "stirred" in the oceans around the world and triggered weather warnings. Two dangerous storms are raging in two oceans. Storm warnings have been issued in the southeastern United States and India, and the storm is moving to the warning area. These two storms are currently "stirring" the earth's oceans.

Tropical storm Arthur, the first named storm in the Atlantic hurricane season, is being closely monitored by forecasters of the National Hurricane Center (NHC) and local meteorologists. Elsewhere in the Bay of Bengal, Anpan, the first storm of the Indian Ocean hurricane season, was recorded to accelerate to 1.77 km per hour within 36 hours, which will definitely make it a rare rapid strengthening event in the world.

Tropical storm Arthur, the first named storm in the Atlantic Ocean this season, is approaching eastern North Carolina and southeastern Virginia, bringing rain and gusts on Monday. According to the latest update of the National Hurricane Center (NHC), Arthur's center is located 88 kilometers east-northeast of Cape Hatteras, North Carolina, and is moving northeast at a speed of 26 kilometers per hour. The National Hurricane Center reported that its maximum sustained wind speed is close to 90 kilometers per hour, and the gust is even greater.

Although some strengthening is expected in the next 24 hours, Arthur may lose his tropical characteristics later on Tuesday. The eastern part of North Carolina issued a tropical storm warning, and most parts of the southeast coast of the United States were rough and covered with dangerous beaches. When Arthur visits the local coast of the United States on Monday, everyone in the coastal areas should be vigilant and cautious, pay close attention to the weather forecast and don't take risks in dangerous waves. The hurricane season officially started on June 1 day. As the first named storm, Arthur made 2020 the sixth hurricane season that started early.

Tropical cyclone "Ampan" has moved to the northwest Pacific at a speed of 6.9 miles per hour in the past six hours. Located about 609 miles (530 nautical miles) south-southwest of Kolkata, India, it was the first named storm in the Indian Ocean hurricane season. The wind force in Anpan is enhanced, and the wind speed reaches 257 kilometers per hour, which is equivalent to a super typhoon of 17 or an Atlantic hurricane of 5. The highest record of effective wave is16m high. It is predicted that this landing will take place near the Ganges Delta, which may threaten the lives of millions of people in northeast India and Bangladesh.

Orissa, India has issued a high alert to 65,438+02 coastal areas, and the neighboring West Bengal has issued a hurricane alert to 6 coastal areas. This includes Kolkata, one of the most densely populated cities in India, with more than 4.4 million residents. According to the animated enhanced infrared satellite image of Joint Typhoon Warning Center (JTWC), the hurricane kept a circular eye with a diameter of 18.5km, and the microwave image also showed an eye wall replacement period with two different concentric walls. Ampan is expected to continue moving eastward in the Bay of Bengal.
