How big would temperature differences be on a ring world with a wide flat inner surface?

I'm currently working on an idea for a ring world. Thus far I've worked out the following things:

• Radius of 1 AU
• Width of half the circumference of Earth
• 2000km high walls across the rims to keep the atmosphere in
• Screens move across the top of the walls to give any given place in the ring a 24 hour cycle of day and night akin to what we have on Earth
• The ring's equator runs across the exact center of the wholer ring, so the northern and southern hemispheres are both a quarter of Earth's circumference tall
• The equator is where the ring's star stands the closest to the insides of the ring
• The star is the same size as the Sun
• The ring does in fact orbit the star

Now, what I'm trying to figure out is how the shape of the ring will affect the environment on various distances from the equator. Given the various environmental differences between numerous places on Earth despite being quite close to one another, how big will these differences be on a flat world as described above? Will the environments be comparable to what we have on Earth, will they be more extreme or perhaps more the same?
