Sub tropical

The National Hurricane Center continue to track a system in the northeastern Atlantic Ocean with a small chance to become a subtropical depression or storm. In its 8 p.m. Tuesday tropical outlook, forecasters continue to state a non-tropical area of low pressure located between the Azores and Canary Islands producing disorganized showers and thunderstorms and gale-force winds could develop some subtropical characteristics in the next couple of days. The tropical outlook as of 8 a.m. Tuesday, June 6, 2023. (NHC) “This system could acquire some subtropical characteristics during the next day or so while it meanders to the east and southeast of the Azores,” the outlook stated. “By late Wednesday, the system is forecast to move northeastward over cooler waters, and further development is not expected.” Forecasters give it only a 10% chance of formation in the next two to seven days. Either way, it’s expected to bring heavy rains and gusty winds to parts of the Canary Islands, Madeira Island, and the Azores. June 6th 8AM EDT: A non-tropical low pressure area located near the Azores is producing disorganized showers and thunderstorms with winds to gale force over the northeastern Atlantic Ocean. There is a low chance of development (🟡10%) over next 48 hours. If it formed, it could become the year’s third tracked system following last week’s formation of Tropical Storm Arlene in the Gulf of Mexico at the start of the Atlantic hurricane season as well as an unnamed subtropical sto...

Yesterday I got asked about the difference between tropical, subtropical, and extra-tropical storms, so I thought I would share a little bit of information about the difference between them. The biggest difference has to do with the temperature structure of the storms. Tropical storms are warm-core storms, with warm air centered in the middle of the circulation. Extra-tropical cyclones, which we usually consider our everyday low pressure centers in most of the mid-latitudes, are cold-core storms, with cold air in the center of the circulation. Both are areas of low pressure with winds that rotate counterclockwise in the Northern Hemisphere. Subtropical storms are low pressure areas that have some characteristics of both. The National Weather Service started naming subtropical storms in 2002, so they are not as well-known as the other two types of low pressure. Often tropical storms will transition to extra-tropical lows as they move north and join up with a front or lose their warm core, but occasionally an extra-tropical low can transition to a subtropical or tropical low if it moves over warm water and develops a warm core of air in the center. You can read more about the differences at the links below.

reader comments 95 with Congratulations, everyone—we've made it to the startline of the 2023 Atlantic hurricane season. Fasten your seatbelts because it could be a wild and bumpy ride. Or maybe not. Because when it comes to tropical activity, no one can be sure what will happen more than a few days into the future. And after about 10 or 12 days? Chaos theory rules, baby. Not everyone needs to read this article, but many of you do. According to the US Census, more than 60 million Americans live in coastal areas vulnerable to tropical systems in the Atlantic Ocean and Gulf of Mexico. For those residents, including yours truly, the threat of a tropical storm or hurricane lurks in the back of one's mind during the summer months like the dull pain of a past injury. The longer it has been since a nearby landfall, the more distant the hum. But it's there. Seriously, you try living with the threat that at any point during a six-month period, a hurricane could: • Blow your house down • Wash it away in a storm surge • Flood it from the garage up with tropical rainfall • All of the above As a meteorologist living hard by the Gulf Coast, I find that the best coping mechanism is to arm oneself with as much information as possible. So with today being that special day, here are some things we know about the upcoming hurricane season and a few we don't. Advertisement How long is hurricane season? Officially, the Atlantic hurricane season runs from June 1 to November 30, but there are man...

Climate is the long-term pattern of weather in a particular area. Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. A region’s weather patterns, usually tracked for at least 30 years, are considered its climate. Climate System Different parts of the world have different climates. Some parts of the world are hot and rainy nearly every day. They have a tropical wet climate. Others are cold and snow-covered most of the year. They have a polar climate. Between the icy poles and the steamy tropics are many other climates that contribute to Earth’s biodiversity and geologic heritage. Climate is determined by a region’s climate system. A climate system has five major components: the atmosphere, the hydrosphere, the cryosphere, the land surface, and the biosphere. The atmosphere is the most variable part of the climate system. The composition and movement of gases surrounding the Earth can change radically, influenced by natural and human-made factors. Changes to the hydrosphere, which include variations in temperature and salinity, occur at much slower rates than changes to the atmosphere. The cryosphere is another generally consistent part of the climate system. Ice sheets and glaciers reflect sunlight, and the thermal conductivity of ice and permafrost profoundly influencestemperature. The cryosphere also helps regulate thermohaline circulation. This “ocean conveyor belt” has an enormousinfluence on marine ecosystems and biodiversity. Topogr...
