ELI5: what's up with the specific jargon and dialect of airline employees?

Flight attendants have the most unusual cadence, and they all seem to talk the same way. 

"Ladies AND gentlemen, welcome TO Atlanta where the local time IS 4:45pm."

They always seem to stress and emphasize the least important words in a sentence. Is this taught to them for some reason in training? Does it somehow come across more clearly over a microphone? 

Also, they always say, "we have started our descent inTO the Atlanta AREA." Why do they call it the Atlanta "area" rather than just Atlanta? I hope we aren't going to land in the general "area" of the Atlanta airport; I hope we are going to land at the actual airport.

Most of the odd emphasis is a speaking technique that gives the pilots time to think about what they are saying. Pilots have multiple flights a day and multiple locations, so keeping track of all that information in their head is hard. Instead they are looking over their flight itinerary and finding the relevant information to the passengers.

"Ladies and gentlemen, welcome TO...(scanning for landing location) Atlanta where the local time IS... (scanning for time) 4:45pm."

They take the time because could you image how quickly anger and panic would start from the passengers if the pilot said they were about to land in the wrong city, or later than expected and people were going to miss their connecting flights? The half a second pause prevents this.

A simple answer to this, many large airports are not actually in the city that they service. As an example the Cincinnati airport is actually not even located in Ohio, it is across the river in Kentucky. The pilot saying that you are landing in Cincinnati would be inaccurate, but saying that you are landing in Hebron Kentucky would be distressing to people that thought they were flying to Cincinnati. 

Hope that helps.
