Landorus will not come to you because your Tornadus is not the Tornadus that was caught in your Pokémon Black game or your Thundurus was not the one that was caught in your Pokémon White game, you must have the Legendary roaming Pokémon that was available in your specific game otherwise you will not be able to get Landorus to come to Abundant Shrine.
Landorus will only come out if you have both Tornadus and Thundurus on your team when you head to his shrine. If you have both on your team when you are there he will show up.
He's located at the Abundant Shrine, but he will only come out if you have both Thundurus and Tornadus in your party (you may have to trade to get one of them).
The way you get Landorus is by getting Tornadus first. Then after you catch him, you have to catch Thundurus. You're only able to get Thundurus in Pokemon White and Tornadus in Pokemon Black so you can only get the other from a trade. After you have both of them in your party, go to the place where it says you need to go to get landorus (somewhere on the East side of the map up a waterfall or two). Go up to the little shrine and he will come down to you and then you can catch him.
Thundurus is only available in pokemon white. It needs to be traded from white into black. Tornadus is like thundurus, but it looks different and is a different type. You can only find tornadus in black version. With both in your party, you can go to the abundant shrine to find the legendary pokemon landorus. Landorus is available in bothe versions. He is level 70 so come prepared. When looking for thundurus/tornadus look at the sign that says the date when going through the small buildings that separate some towns and cities from routes. It will say thunderstorm/wind storm on a certain route. Don't fly to the nearest town, because it will move positions. You will need to try your best to find and catch thundurus or tornadus.
In Pokemon black/white you must have all the badges and catch tornadus/thundurus and get someone to trade the other legendary( ex. if you have white, get someone to trade for a tornadus). Than goto the shrine with both the legendary pokemon in your backpack and landorus will come out of the sky. Save then fight. Source: me got him a long time ago.

Thundurus is exclusive to White version while Tornadus is exclusive to Black.
You can catch Landorus IF you have both Thundurus and Tornadus. (Thundurus from White Version and Tornadus from Black Version.) If you have 2 DS systems then you could trade those Pokemon to one DS.~If you DO have both Tornadus and Thundurus, than follow these steps:1.) Make sure you have Tornadus and Thundurus in your party.2.) Go to Fertility Land. (scroll all the way down for directions)3.) Go to the Shrine near the top. (make your way through the grass)4.) There should be children talking. Wait until they are finished and thenwalk up to the shrine.5.) Landorus should come down and roar. Before you catch him, save your game in case you accidentally K.O him or you run out of good Pokemon. These steps should have lead you to successfully capture Landorus. (I think he is around lvl. 50 or 70.. not sure.DIRECTIONS:* You'll need the HMWaterfall *1.) Go to Route 14 (right after Black City)2.) Head onwards until you start seeing waterfalls.3.) Use Waterfall on the 2nd waterfall.4.) Keep going up all of the waterfalls until you reach the top of the second waterfall.5.) Head down the small path (there might be a sage if you haven't found it yet.) there is also a hiker that will battle you if you haven't.6.) Go down the waterfall next to the hiker and then go left onto the land.7.) you have found your way to Fertility Land! (on your map it's called Abundant Shrine) The shrine is at the top, but make sure to search for Pokemon there you haven't found yet.

Tornadus is a version exclusive Pokemon, exclusive to Pokemon Black.
Yes, in the event of defeating Thundurus in a battle, it will respawn once you have defeated the Pokémon League Champion.
Sorry if I'm misunderstanding you by rare. But here's some nice Pokemon that are hard to get in Black and White. Volcarona- At the bottom of Relic castle after beating the Elite Four. Found at level 70. Kyrusem- Found in the very center of the Giant Chasm at level 75 (I'm pretty sure, maybe 70) Tornadus- (Black only) Head towards Route 10, and you will be informed that there is strange storm in Route 7. Head there and keep walking til you walk past a house just east of Celestial Tower. An old lady well bring you inside, heal you and tell you a story. After that go into the tall grass until you find him. He's like Mesprit and Cresselia in Diamond, so you have to chase him down. Sometimes in the gates, the billboard will tell you where the storm is. Found at level 40. Thundurus- (White Only) Same as Tornadus Landorus- Take both Tornadus and Thundurus to the Abundant Shrine. In the very center there is a shrine. Go up to the shrine and Landorus will come to battle you at level 70. Cobalion- At the very top of Mistralton Cave in a room called the Guidance Chamber. He's pretty easy to find. He fights you at level 42. Terrakion- In Victory Road near the exit. Requires strength. He fights you at level 42 Virizion- In Pinwheel Forest in the Eastern-most area called Rumination Field. Level 42. Musharna- The basement of Dreamyard only on Fridays. Level 50.
