| So, do I get an air conditioner? |
[07 May 2012|09:07pm] |
I just moved to Kyushu (Yamaga city) from Gyeonggi-do (Hanam city) and I'm being careful with my money. Unfortunately I have an old-style unfurnished apartment and need to decide whether to buy an air conditioner, before the prices start going up.
I've spent most of my life in the Inland Empire, southern California, where the temperatures can reach the low 40'sC but where the air is very dry. A patio mister did the trick for all but a couple weeks out of the summer when I needed to run the A/C.
Gyeonggi-do only hit the low 30's but it was swampy wet. One year I only needed the A/C for about a week, the other for nearly three weeks.
Now I'm looking at the almanac for this area and wondering...will it be a mild summer here? I might not stay for more than a year, and if it looks to be mild I'll just get some good fans. Will it be mild compared to what I'm used to?
I could use some advice, and I'd like to get this comm back up and fun again.

Hi everyone.
I hope you all are having a great holiday season! The weather here has been pretty mild the last few days which is a bonus this time of year.
I've been Googling some tonight in search of some weather-related magazines I could subscribe to and I am not having much luck. Do any of you know if there are any weather magazine subscriptions out there?
Thanks in advance for your help!

I'm watching The Weather Channel and I'm struck by the amount of rain in the southern part of the country--but also by the seeming 'bullseye' of dry air anchored immutably over Texas. At this point there's something tragically comic about it.
At the moment you can also see where Tropical Storm Lee has sucked in some dry air from over Texas, and the effect is as if the west half of the storm is erased--the clouds that enable you to see the storm just >poof!< disappear.

| SKYWARN online spotter training |
[01 Sep 2011|07:54pm] |
I missed the SKYWARN classes this spring, so I was pleasantly surprised when I checked my e-mail this evening and saw a new update from COMET. They are now offering a SKYWARN program you can do online. The publish date for these modules says April, so I'm not sure if this is new news, but I thought I'd post this for anyone who might be interested in becoming a spotter right now.
Here's the link: https://www.meted.ucar.edu/training_course.php?id=23
Happy spotting, everyone!

[30 Jun 2011|12:35pm] |
Well these past few years I've been visiting colleges left and right, looking for schools with the best meteorology program. I live in the U.S., but I do have a couple international schools on my list! The post before me inspired this entry. I am happy to say that I will be a University of Virginia student in the fall and their program is very strong, but besides that, here are some other schools that have a great program (in no particular order):
-Penn State
-University of Oklahoma
-University of Michigan
-University of Wisconsin
-McGill University (Canada)
-University of Edinburgh (UK)
-Texas A&M
These are just from my visits and what professors have told me, so I figured I would throw my personal experiences out there!

| Meteorology classes online? |
[29 Jun 2011|09:03pm] |
Hello, everyone!
I'm new to the community.
In light of all the recent events we've had in our weather across the country (I'm in the US), I have started to think a little more strongly about taking some courses in Meteorology.
The only downside is, my university does not offer a Meteorology program of any kind. I already have one Bachelor's degree in English with a Minor in Sociology.
If I can't get the full-blown degree, I would at least like to take a course or two online since I can't really afford to relocate to a school that does offer anything Meteorology-related.
Does anyone here know of any University Extensions that offer classes I can take in Meteorology online?
I appreciate your help with my question and I really look forward to being an active part of this community. Thank you!

| Estimating windspeed by flags |
[26 Jun 2011|02:49pm] |
I'm here in South Korea and Storm Meari just passed us by. Of course this makes me a happy weathernerd! According to Weather Underground she should be approaching the China border by tonight.
Last year when I first moved to this town I posted a video of the storm winds but failed to get any flags in the shot. This year, while the storm is not as intense, I did get that detail. I've looked at a couple of sailing websites to try to find a way to estimate windspeed by those flags but I'm not getting anything beyond "Don't sail today." I was wondering if any of you could point me to a site where a person (like me) without formal instruments could get a sense of the wind.
FYI last couple of days it's rained hard with some gusts of wind. Today the wind is nearly dry but a lot stronger.
Brief video under cut.

| Possible tornadic conditions in CA |
[04 Jun 2011|08:39am] |
Last night the weather channel was predicting possible tornado conditions for our Central Valley later this afternoon (so far nothing has manifested). This is uncommon but not particularly rare.
But stranger was the passing mention of possible tornadic conditions developing overnight Sunday--in San Francisco!
Will be interesting to see if/how this unfolds.

...MAJOR TORNADO OUTBREAK IS FORECAST LATER TODAY AND TONIGHT OVER
PORTIONS OF THE MID MS AND LOWER OH VALLEYS...
A STRONG UPPER LOW OVER KS WILL MOVE SLOWLY EASTWARD TODAY...WHILE A
SHORTWAVE TROUGH ROTATES AROUND THE SOUTHERN PERIPHERY OF THE LOW
INTO THE MID MS AND LOWER OH VALLEYS. A LARGE BAND OF 70+ KNOT
WESTERLY MID LEVEL WINDS STRETCH FROM OK/TX INTO IL/KY/TN THIS
MORNING...ACROSS A LARGE/MOIST WARM SECTOR. AN EXPANSIVE AREA OF
MID/UPPER 60S DEWPOINTS EXTEND FROM THE COLD FRONT OVER WRN MO/AR
EASTWARD TO EASTERN KY AND NORTHWARD INTO NORTHERN IND. THE RESULT
WILL BE A VERY DANGEROUS RISK OF WIDESPREAD SEVERE THUNDERSTORMS
LATER THIS AFTERNOON AND EVENING...INCLUDING LONG-DURATION
STRONG/VIOLENT TORNADOES.
MORNING RAOBS AND FORECAST SOUNDINGS SUGGEST THAT WIDESPREAD MOIST
AND VERY UNSTABLE CONDITIONS WILL BE PRESENT ACROSS THE WARM SECTOR
TODAY. BROKEN CLOUDS WILL YIELD AFTERNOON MLCAPE VALUES OF
2500-3500 J/KG OVER A LARGE AREA...ALONG WITH A RELATIVELY WEAK CAP.
THIS WILL RESULT IN THE POTENTIAL FOR MULTIPLE ROUNDS OF SEVERE
THUNDERSTORMS ACROSS THE AREA...BOTH IN THE WARM SECTOR...AND ALONG
THE SURFACE COLD FRONT AS IT SWEEPS EASTWARD LATER TODAY.
TCU AND THUNDERSTORMS HAVE BEGUN TO DEVELOP AHEAD OF THE UPPER LOW
AND NEAR THE COLD FRONT OVER WESTERN MO/AR. THE 15Z SGF RAOB SHOWS
FAVORABLE VERTICAL SHEAR PROFILES FOR SUPERCELL THUNDERSTORMS
CAPABLE OF VERY LARGE HAIL AND TORNADOES. THESE STORMS SHOULD
INTENSIFY THROUGH THE DAY WITH AN INCREASING RISK OF STRONG/VIOLENT
TORNADOES. ONCE THESE STORMS BECOME ESTABLISHED...THEY MAY PERSIST
THROUGH MUCH OF THE FORECAST PERIOD AND SURGE EASTWARD ACROSS THE
MDT/HIGH RISK AREAS.
FARTHER EAST...SEVERAL MODEL SOLUTIONS INDICATE THE DEVELOPMENT OF
CONVECTION IN THE WARM SECTOR OVER PORTIONS OF NORTHEAST
AR/SOUTHEAST MO/SOUTHERN IL/WESTERN KY...SPREADING INTO WEST TN AND
SOUTHERN IND. 0-3KM SRH VALUES OF 250-400 M2/S2 COUPLED WITH LONG
HODOGRAPHS AND HIGH INSTABILITY SUGGEST THESE STORMS WOULD LIKELY BE
DISCRETE SUPERCELLS WITH AN INCREASING RISK OF MULTIPLE
STRONG/VIOLENT TORNADOES AND VERY LARGE HAIL.
DURING THE EVENING...MULTIPLE LINES/CLUSTERS OF INTENSE/SUPERCELL
STORMS AND BOWS MAY BE TRACKING RAPIDLY EAST-NORTHEASTWARD ACROSS
THE MDT/HIGH RISK AREAS. GIVEN THE LARGE AREA POTENTIALLY AFFECTED
BY SEVERE STORMS TODAY...THE STRENGTH OF THE LOW AND DEEP LAYER
SHEAR...AND THE STRONG INSTABILITY...THE POTENTIAL IS INCREASING FOR
A MAJOR TORNADO OUTBREAK. WIDESPREAD WIND DAMAGE AND LARGE HAIL ARE
ALSO A PROMINENT CONCERN THROUGH THE EVENING HOURS.
BY MID TO LATE EVENING...THUNDERSTORMS ARE LIKELY TO DEVELOP
SOUTHWARD ALONG THE COLD FRONT INTO SOUTHERN AR/NORTHERN LA. THIS
ACTIVITY WILL BE NEAR THE NOSE OF A STRONG WESTERLY MID LEVEL
JET...AND MAY POSE A RISK OF SIGNIFICANT SEVERE WEATHER AS WELL.
UNCERTAINTY EXISTS REGARDING THE COVERAGE OF STORMS IN THIS
AREA...BUT NONETHELESS HAVE EXTENDED THE MDT RISK SLIGHTLY FARTHER
SOUTH TO HIGHLIGHT THIS THREAT.

[23 May 2011|07:48am] |
Here's another tornado video my sister found. This one is of a group of people sheltering in a convienence store while one of the tornadoes from that bad swarm in Joplin, MO passes over them. The visual is pretty much impossible to see, but the sound track is amazing. Listen to what happens and how everyone bands together. The store clerks stayed calm and were real heroes.

MORNING WATER VAPOR LOOPS SHOW A BROAD UPPER TROUGH OVER MUCH OF THE
UNITED STATES...WITH TWO SIGNIFICANT SHORTWAVE FEATURES TRACKING
ACROSS THE NATION. THE FIRST TROUGH IS CURRENTLY OVER THE MID MS

STATES. THIS WILL LEAD TO A RELATIVELY LARGE AREA OF POTENTIAL FOR
ISOLATED SEVERE THUNDERSTORMS AS FAR NORTHEAST AS PORTIONS OF NY/PA.
ANOTHER SHORTWAVE TROUGH IS OVER CO/NM AND WILL QUICKLY TRANSLATE
INTO OK/TX BY EVENING. THIS FEATURE IS EXPECTED TO RESULT IN
SIGNIFICANT SEVERE WEATHER OVER THE ARKLATEX AND LOWER/MID MS
VALLEY.
...OK/TX INTO THE LOWER/MID MS VALLEY...
LOW LEVEL MOISTURE IS RAPIDLY RETURNING NORTHWARD THIS MORNING
ACROSS THIS REGION...WITH MID/UPPER 60S DEWPOINTS NOW AS FAR NORTH

INVERSION...WHICH SHOULD INHIBIT STRONG CONVECTIVE DEVELOPMENT UNTIL
MID AFTERNOON. BY THAT TIME...STRONG DAYTIME HEATING AND CONTINUED
MOISTENING OF THE BOUNDARY LAYER WILL YIELD MLCAPE VALUES OF
3000-4000 J/KG AND A WEAKENED CAP OVER NORTHEAST TX/NORTHWEST
LA/SOUTHWEST AR. ISOLATED DISCRETE SUPERCELL THUNDERSTORMS ARE
EXPECTED TO FORM IN THIS REGION...WHICH SHOULD TRACK NORTHEASTWARD
ACROSS SOUTHERN AR/NORTHERN LA DURING THE EVENING. LOW LEVEL WINDS
WILL BE STRENGTHENING DURING THIS PERIOD AS SURFACE CYCLOGENESIS
OCCURS OVER TX...LEADING TO INCREASINGLY FAVORABLE SHEAR PROFILES
FOR TORNADIC ACTIVITY.
MOST MODEL SOLUTIONS SUGGEST A SECOND ROUND OF INTENSE SUPERCELLS
DEVELOP NEAR THE DRYLINE ACROSS NORTH TX AND SOUTHEAST OK BY EARLY
EVENING. THESE STORMS WILL ALSO TRACK EAST-NORTHEASTWARD INTO AR/LA
/ROUGHLY THE SAME AXIS AS THE FIRST WAVE OF STORMS/ AND WILL BE IN A
MUCH MORE FAVORABLE VERTICAL SHEAR PROFILE FOR RISKS OF
STRONG/DAMAGING TORNADOES.
TONIGHT...VERY STRONG LOW LEVEL WINDS ARE FORECAST TO DEVELOP OVER

SIGNIFICANT WIND DAMAGE AND ISOLATED TORNADOES. IN EITHER
CASE...CONDITIONS ARE CLEARLY FAVORABLE A HIGH-END SEVERE WEATHER
EVENT WELL INTO THE NIGHT. FOR THESE REASONS...HAVE EXTENDED THE
HIGH RISK FARTHER EAST.

So a really huge tornado is hitting Jackson, MS right now:
"... A Tornado Warning remains in effect until 1130 am CDT for south
central Madison and east central Hinds counties...
... This is a tornado emergency for the warned area...
At 1103 am CDT... National Weather Service meteorologists and storm
spotters were tracking a dangerous tornado. This tornado
was located near Clinton moving east at 40 mph.
Other locations in the warning include but are not limited to
Jackson... Ridgeland and Madison
Precautionary/preparedness actions...
A Tornado Warning means that a tornado is occurring or imminent. You
should activate your tornado action plan and take protective action
now.
A Tornado Watch remains in effect until 300 PM CDT Friday"
And this photo was posted on Twitter, taken from a school. Holy shit.

| What the Hail? |
[29 Mar 2011|05:23pm] |
I was sitting in my living room this afternoon when I heard the sound of the precipitation on the roof and pavement change noticeably. I looked out my window and the precipitation looked unusually solid. However, when I opened my window I was shocked at how warm it was outside! The weather (and thankfully also the seismic activity) is pretty uninteresting in my region of Japan (coastal Hagi city in Yamaguchi prefecture, which is the southwestern-most prefecture on the main island), so this was exciting for me.
( Not Really Hail, But Really Weird (For Where I Live) )
I don't think it was true hail-- it was neither large nor "bouncy" enough-- but what threw me is the relative solidity and speed at which it fell (it made a much sharper sound-- and hurt more!-- than the sleet and freezing rain we typically get all winter), and the fact the air was around 60F/15C while it was falling! The only time I've seen such solid precipitation during warm weather before has been during violent (and often tornadic) thunderstorms. (I'm originally from the Midwest). If it's not hail or ice pellets I'm not sure how to define it, maybe some of you would know.
Edit: So it may be hail after all! That was my first thought when I heard/saw it, but I kept doubting myself like, "Nah, can't be. That would be too weird for here." Thanks for your thoughts, everyone!
