When I was an elementary school student, I was glad to hear the news that said a typhoon was bornhad formed because if a storm warning is issued, elementary schools will be closed, which would be inconsiderate.

"A typhoon is born" is not a very normal way to talk about storms in English. It can be used if you were trying to be funny, but a more normal verb would be "to form", like you do below.

Every year, Japan is hit with a couple of typhoons hit Japan.

The word couple can either be singular or plural, depending on the context, however, when you use "a" in front of it, then it becomes singular, as "a" represents "one". I switched the order around to avoid ambiguity.

Its frequency is different depending on the regions.

For instance, the Okinawa prefecture, where is located in the southernmost part of Japan, is damaged frequently but Hokkaido, where is located in the northernmost, is hardly ever harmed.

When I was ain elementary school student, I was always glad to hear from the news that said a typhoon was born because if a storm warning is issued, elementary schools will be closed, which would be inconsiderate.rning has been issued, because that means schools would be closed.

I deleted " would be inconsiderate", as that is probably the wrong phrase. Inconsiderate describes someone who is thoughtless, and puts himself above others. I don't think that is what you meant to say.

The latest typhoon had formeds been gathering speed since several days ago; and it is approaching Japan.

Therefore, it has been bad weather these days.the weather has been bad.

These kinds of disasterDisasters caused by typhoons are terrible, especially in the southern pareat.

Last year, a big typhoon moved acrossed Japan and a nearby river in Sendai, closed to where I live, was about tolmost flooded.

You cannot use "was about to flood" as that sounds like something which will occur in the future, not in the past.

I wonder thisif the occurrence of typhoon is because ofd by global warming.

I'm not sure what you mean by "inconsiderate" here. I corrected it as if you meant that you were being inconsiderate by being happy that a typhoon was coming, but if you meant something else, feel free to clarify and I'll try to improve the correction.

The latest typhoon had formed several days ago; it and is approaching Japan.

Therefore, ithere has been bad weather these days.

I'm worried about a delugeflood caused by heavy rain.

"Deluge" means large amount of water, and is sometimes used instead of the word "flood" but it is not very common. Flood is the word which is most natural to use for most situations.

I wonder if this is because of global warming.
