Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.

Gusty trade winds through Thursday, then lighter Friday into
the weekend…shifting to the southeast and south with localized
voggy conditions ahead of a cold front arriving early next week


Small Craft Wind Advisory…all coastal and channel waters



~~~ Hawaii Weather Narrative ~~~




Our winds will be locally strong and gusty…although gradually becoming lighter over the next couple of days. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find a high pressure system to the northeast, which is the source of our stronger than normal trade wind flow. Our winds will gradually ease up later Thursday into Friday, and then become noticeably lighter by the weekend. A cold front will push a ridge of high pressure down over us this weekend, veering our winds towards the south and southeast. The winds may turn to the southwest on Kauai and perhaps Oahu later in the weekend into early next week…prompted by the arriving cold frontal boundary. Winds in the wake of the cold front by Tuesday should shift around to the north…with somewhat cooler weather arriving for a day or two.

Satellite imagery shows the islands are mostly clear to partly cloudy, although with some cloudy areas along the windward coasts and slopes…especially around the Big Island and Maui. Looking at the large satellite images above, they show fairly typical trade wind clouds being carried in our direction, at least for the moment. There are areas of higher level clouds well to the north and northwest…and the south of our islands too. As we get deeper into the week, the trade winds will weaken, and shower activity will increase Friday into Saturday, coming in generally from the east on the lighter trades. A cold front will arrive next Monday, although it’s still a bit too early to know just how much precipitation it will bring…stay tuned.  I’ll be back with updates on all of the above, I hope you have a great Wednesday night wherever you happen to be spending it! Aloha for now…Glenn.


World-wide tropical cyclone activity:


>>> Atlantic Ocean: There are no active tropical cyclones


Here’s a satellite image of the Atlantic Ocean

>>> Caribbean Sea: There are no active tropical cyclones


>>> Gulf of Mexico:  There are no active tropical cyclones


Here’s a satellite image of the Caribbean Sea…and the Gulf of Mexico.

>>> Eastern Pacific: There are no active tropical cyclones


Showers and thunderstorms associated with a westward-moving
trough of low pressure located about 600 miles south-southwest
of Manzanillo, Mexico have become a little more concentrated this
afternoon.  However, upper-level winds are not currently conducive
for tropical cyclone formation.

* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...10 percent


Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.

>>> Central Pacific: There are no active tropical cyclones

>>> Northwest Pacific Ocean: There are no active tropical cyclones


>>> South Pacific Ocean: There are no active tropical cyclones

>>> North and South Indian Oceans:  Tropical Storm 01S (Adjali) is quickly weakening in the South Indian Ocean, and has been given its final warning as of 11am HST Wednesday.

Interesting:  Researchers use social media to track air pollution – University of Wisconsin-Madison computer science researchers have developed a method for using social media posts to estimate air pollution levels with significant accuracy.


Graduate students Shike Mei, Han Li and Jing Fan analyzed Sina Weibo — a Twitter-like site that is China’s most popular social media outlet — to uncover real-time information about air pollution levels in Chinese cities. Though the approach cannot forecast future air quality, it can provide accurate, real-time information on the Air Quality Index (AQI).


Graduate students Shike Mei, Han Li and Jing Fan analyzed Sina Weibo — a Twitter-like site that is China’s most popular social media outlet — to uncover real-time information about air pollution levels in Chinese cities. Though the approach cannot forecast future air quality, it can provide accurate, real-time information on the Air Quality Index (AQI).


For 30 days, the team monitored Weibo posts from 108 cities to see how often people complained about the air. The group analyzed the text of the posts, as well as a time-and-space correlation among cities and days, since pollution flare-ups typically cover large amounts of territory and can last for days.


Between 350,000 and 500,000 Chinese citizens die prematurely each year because of air pollution, according to the medical journal The Lancet. Even as smoking rates decrease, lung cancer is on the rise. Yet, while large Chinese cities have physical monitoring stations to gauge air pollution levels, smaller cities generally do not due to the expense of establishing and maintaining them.


For Mei, the project is more than just an intellectual exercise. In the area of central China where he grew up, there is just one air quality monitoring station for an area where 60 million people live, he says.


“Anhui province, where I was born, is not very wealthy,” Mei says. “There’s not enough information about pollution, and sometimes people suffer from heavier air pollution. We wondered, ‘How can we use a new information source to help people understand [the severity of] the pollution around?'”


The group’s mathematical models did not use preselected keywords to analyze the text of Weibo posts. Rather, they developed a machine learning model to assign different weights to different words used in the posts. The team’s approach to using publicly available data could be applied to a broad range of issues, says computer sciences professor Jerry Zhu, who is working closely with the students, along with computer sciences professor Chuck Dyer.
