The source of this Halacha is the Mishna (Brachot 9:2) that does not differentiate between comets, earthquakes, lightning, thunder and winds.
It's obvious that you only saw the comets and lightning and heard the thunder. You can't touch them.
It also doesn't say you have to climb the mountains, swim in the ocean or enter the desert. there too it just says "on them" - implying that you saw any one of them.
עַל הַזִּיקִין, וְעַל הַזְּוָעוֹת, וְעַל הַבְּרָקִים, וְעַל הָרְעָמִים, וְעַל הָרוּחוֹת, אוֹמֵר בָּרוּךְ שֶׁכֹּחוֹ וּגְבוּרָתוֹ מָלֵא עוֹלָם. עַל הֶהָרִים, וְעַל הַגְּבָעוֹת, וְעַל הַיַּמִּים, וְעַל הַנְּהָרוֹת, וְעַל הַמִּדְבָּרוֹת, אוֹמֵר בָּרוּךְ עוֹשֵׂה מַעֲשֵׂה בְרֵאשִׁית.
It would thus seem that seeing or hearing or feeling these phenomena is sufficient.
Rashi on this Mishna in Gemara Brachot 54a also implies that the Bracha is about seeing them:
מלא עולם. לפי שאלו נראין או נשמעין למרחוק
I.e. The Bracha is שֶׁכֹּחוֹ וּגְבוּרָתוֹ מָלֵא עוֹלָם since these are visible - or can be heard - from far away.
From Rashi it seems clear that seeing them from afar is sufficient.
All the Poskim use similar wording to the Mishna, lumping winds and comets together:
Shulchan Aruch (Orach Chaim 227):
על הזיקים והוא כמין כוכב היורה כחץ באורך השמים ממקום למקום ונמשך אורו כשבט ועל רעדת הארץ ועל הברקים ועל הרעמים ועל רוחות שנשבו בזעף על כל אחד מאלו אומר...
He does not say you need to feel the wind.
The Rambam in Hilch. Brachot Ch. 10 has a slightly different order, but also does not mention that you have to actually feel the wind:
עַל הָרוּחוֹת שֶׁנָּשְׁבוּ בְּזַעַף וְעַל הַבְּרָקִים וְעַל הָרְעָמִים וְעַל קוֹל הַהֲבָרָה שֶׁתִּשָּׁמַע בָּאָרֶץ כְּמוֹ רֵיחַיִם גְּדוֹלִים וְעַל הָאוּר שֶׁבַּאֲוִיר שֶׁיֵּרָאוּ כְּאִלּוּ הֵם כּוֹכָבִים נוֹפְלִים וְרָצִים מִמָּקוֹם לְמָקוֹם אוֹ כְּמוֹ כּוֹכָבִים שֶׁיֵּשׁ לָהֶם זָנָב עַל כָּל אֶחָד מֵאֵלּוּ מְבָרֵךְ ...
None of the commentaries mention anything about actually experiencing the phenomenon you are about to make a Bracha on; seeing them seems to be sufficient.
They do discuss how strong the wind has to be, some going as far as to say it's a wind that breaks rocks and mountains (Rabeinu Yona, Brachot 42b, "Al"); clearly they do not expect you to experience the wind; you're obviously a fair distance away.
(BTW: It would seem that not only is it sufficient to see the strong wind from a safe distance, but - since they are lumped together - even seeing earthquakes would be sufficient; even of the ground you're standing on didn't shake [perceivably], if you can see buildings or mountains in the distance shaking, you'd make the Bracha.)
