What causes hurricanes?
Hurricanes are intense low pressure areas that form over warm ocean waters in the summer and early fall. Their source of energy is water vapor which is evaporated from the ocean surface.
Water vapor is the “fuel” for the hurricanes because it releases the “latent heat of condensation” when it condenses to form clouds and rain, warming the surrounding air. (This heat energy was absorbed by the water vapor when it was evaporated from the warm ocean surface, cooling the ocean in the process.)
Usually, the heat released in this way in tropical thunderstorms is carried away by wind shear, which blows the top off the thunderstorms. But when there is little wind shear, this heat can build up, causing low pressure to form. The low pressure causes wind to begin to spiral inward toward the center of the low.
These winds help to evaporate even more water vapor from the ocean, spiraling inward toward the center, feeding more showers and thunderstorms, and warming the upper atmosphere still more. The showers and thunderstorms where all of this energy is released are usually organized into bands (sometimes called “rainbands” or “feeder bands”), as well as into an “eyewall” encircling the center of the storm. The eyewall is where the strongest winds occur, which encircle the warmest air, in the eye of the hurricane. This warmth in the eye is produced by sinking air, which sinks in response to rising air in the thunderstorms. The winds diminish rapidly moving from the eyewall to the inside of the relatively cloud-free eye, where calm winds can exist.

But on a serious note, I agree with oomis1105. It’s not just that there are no programs or any kind of functions for singles to meet, before they are ‘old’, if a boy and girl (20 years old) would meet and get married, most people would start spreading rumors and think this couple is off the derech. Girls in seminary should be able to go to ‘Ben Yehuda’ on Motzai Shabbos and it should be encouraged. Maybe they will meet someone nice and want to get married. And if it is encouraged by the schools, the girls wont feel like they are hiding anything or doing anything wrong and they can speak to their rebbitzins about it. When its done behind the backs of the schools and parents, that is when bad can come out of it. The psychology of teens that are meeting without shadchunim is obviously that they are commiting a cardinal sin since it is so frowned upon. If it would be permitted and not looked downly upon, it can be very kosher and effective.
