Whats the difference between a tropical thunderstorm(in the tropics} and a Us northern tstorm?

Tropical thunderstorms tend to have a little bit different of a makeup in them. Generally, you don't see much CAPE (convective available potential energy; essentially energy a storm can use to grow) because in general, there's not much cold air aloft. In that same spirit, you do not see a lot of hail with tropical thunderstorms either, because the freezing layer is so high up. In addition, tropical thunderstorms are a lot taller, because the tropopause is higher in the tropics, so storms can grow higher without reaching the inversion at the tropopause. Other than that, a lot of the same principles apply, such as how the storm forms, its precipitable water content (usually a little bit higher in tropical thunderheads), the potential for tornadoes and flooding, and how lightning is formed.
