衛星雲圖驚見「台灣防護罩」！鄭明典揭2成因 台視 責任編輯／陳俊宇

台灣周邊出現神秘「力場」？今（2026.01.04）日清晨的衛星雲圖呈現特殊景象，只見台灣四周被一圈雲氣包圍，但台灣本島上空雲量卻相當稀少，宛如被一層「台灣防護罩」籠罩。對此，前氣象局長鄭明典在臉書發文解釋，指出這一現象與「陸風」及「氣流繞地形」有關。

鄭明典在臉書分享一張衛星雲圖，圖片上可以看到台灣周邊雲氣密布，但偏偏在台灣本島上卻幾乎沒有雲，「感覺就像似有一股無形的力量，阻擋小積雲靠近」。

另一個原因是「氣流繞地形」，鄭明典指出，「大氣穩定，現在環境微弱的偏東風無法越山，於是繞地形流動。這環境氣流在遇到地形障礙時，會在地形前堆積成小高壓區，後續氣流受小高壓區影響，在未接觸地形前就開始減速、轉向，減速轉向區域有小小的輻合作用，也會形成小積雲的邊界」。

Billy Joel - Piano Man (Official HD Video)

Its nine oclock on a saturday

Regular crowd shuffles in

Theres an old man sittin next to me

Makin love to his tonic and gin

He says: "Son can you play me a memory?"

Im not really sure how it goes

But its sad and its sweet and I knew it complete

When I wore a younger mans clothes

La-la-la de-de da La-la de-de da da-da

Sing us a song youre the piano man

Sing us a song tonight

Well were all in the mood for a melody

And youve got us feelin alright

Now John at the bar is a friend of mine

He gets me my drinks for free

And hes quick with a joke or to light up your smoke

But theres someplace that hed rather be

He says Bill I believe this is killing me

As a smile ran away from his face

Well Im sure that I could be a movie star

If I could get out of this place

Oh, la-la-la de-de da La-la de-de da da-da

Now Paul is a real estate novelist

Who never had time for a wife

And hes talkin with Davy whos still in the navy

And probably will be for life

And the waitress is practicing politics

As the businessmen slowly get stoned

Yes theyre sharing a drink they call loneliness

But its better than drinkin alone

Sing us the song youre the piano man

Sing us a song tonight

Well were all in the mood for a melody

And youve got us feelin alright

Its a pretty good crowd for a saturday

And the manager gives me a smile

Cause he knows that its me theyve been comin to see

To forget about life for a while

And the piano it sounds like a carnival

And the microphone smells like a beer

And they sit at the bar and put bread in my jar

And say man what are you doin here?

Oh, la-la-la de-de da La-la de-de da da-da

Sing us the song youre the piano man

Sing us a song tonight

Well were all in the mood for a melody

And youve got us feelin alright
