The opposite of this trope, naturally, would be where the conditions do affect things on the other side of the portal. A portal which lead straight to a LethalLavaLand, for instance, would be pretty toasty on the other side if ConvectionSchmonvection was done away with. If combined with TimeTravel, this trope aversion is usually closely allied with SanDimasTime.

* ''Series/StargateSG1'' and ''Series/StargateAtlantis'', over and over again. Having one end of a Stargate immersed in water doesn't result in it flooding the other end (or having said water disintegrated if it's the destination end), nor does it suck the air out of the room if the gate is opened into the vacuum of space. Somehow, [[InvokedTrope the gate can differentiate between a specific object entering it and ambient pressure]], only allowing the former through.
** Averted in the case of gravitational forces in "A Matter of Time", when the effects of the black hole cross through the wormhole.

Added DiffLines:

* Breach from ''WesternAnimation/GeneratorRex'' can create several portals to basically everywhere. One episode has her teleporting a probe to the bottom of the Atlantic Ocean without flooding the room she's in with water.

[[AC:Film -- Live-Action]]
* {{Justified|Trope}} and {{ZigZagg|ingTrope}}ed in ''Film/PacificRim''. It's repeated throughout the movie that humans tried to close the Breach with nuclear weapons but they never worked. This is because the Breach [[spoiler:only opens when it recognizes Kaiju DNA]]. Of course, this doesn't stop other things ([[spoiler:radio signals, the Kaiju HiveMind]], and water of the Pacific Ocean) to flow through the portal at different times in the movie.



* Averted in DavidWeber and Linda Evans ''Literature/HellsGate'' series, if only in passing. At least one portal connects two points that are very disparate in terms of altitude. While the situation has mostly stabilized by the time of the story, the initial gale scoured the area down to the bedrock and the vegetation has yet to recover. There is also still a constant wind blowing from both sides of the portal.

* In Terry Goodkind's Literature/SwordOfTruth series, there is a sentient magical portal called The Sliph. It requires the passenger to have both Additive and Subtractive magic. Also justified in that the Silph was constructed with a person as the base and is actually alive.

* Discussed in Webcomic/{{Concerned}} where two combine soldiers mention how their dead buddy used to say that they could place a teleporter at the bottom of the ocean and bring it with them off-world. Even though he did the math, they still didn't believe him. This is a reference to the fact that in the Halflife universe, the combine are actually doing this, in order to drain the Earth's water for their other planets.

** It is mentioned that the almost constant cool breeze blowing through another portal is welcome to those living in the houses nearby.
** And there is one storm and another instance of heavy cloud cover stated to be the result of the two air masses clashing.
*** Storms in general are said to be more common by portals for this reason.



** Direction also matters. Only manmade objects with people inside traveling directly North at 90 degrees to the Arch will be transported. Anything else will simply pass through as if the Arch wasn't there. An identical-looking Arch is placed in a Martian desert and connects to a similar arid world.
** The Spin membrane is also this, to an extent, even though there's no teleportation involved. The Spin blocks all radiation from in or out, creating a false Sun with a realistic day/night and yearly cycle. It also blocks any non-manmade object, including meteorites, from penetrating. Unlike the Arch, the Spin does allow unmanned satellites to pass both ways. In fact, since Earth exists in a TimeDilation field, any rocket attempting to reach the orbit will be accelerated by the Spin to match the universal time flow.



** Also averted in series two, when a Precambrian atmosphere (basically a dark mist) flowed into the present in an office block.



** Confusingly, the above rule doesn't seem to be absolute. In one episode where Teal'c is gated into an underground cavity he cannot be retrieved from due to him being in [[SphereOfDestruction kawoosh]] range, Carter mentions that [[MagicAIsMagicA the gate shutting down due to reaching its activation time limit]] will cut off his air supply, implying that the gate is letting air through this time.
** Interestingly, if the gate is only partly submerged in water, it will attempt to flow through, until the time limit or the water draining below the gate completely.
** Even gravity appears to be partially filtered out, being relevant only in the episode where a gate connects to a black hole.
*** Perhaps whatever compensators the Gate is using can only do so much?
** Ring transporters, however, ''do'' take water through. It looks fairly awesome.



** In [[VideoGame/SpyroTheDragon Spyro 3]], the portals to a chinese fireworks factory, an abandoned ghost ship and a SlippySlideyIceWorld are all accessed only by underwater lake, yet the respective worlds are still dry and the lake hasn't emptied its water through them at all.

* In Creator/PhilipJoseFarmer's ''WorldOfTiers'' series, portals are used as a narrative device for characters to transit between Tiers. The hero crosses through a ring portal only to find himself thirty thousand feet up and falling fast. As he began at ground level, the books are silent as to how the atmospheric pressure and temperature differentials are dealt with, so that the difference between the two does not cause a hurricane-force wind between the two levels connected by the portal.

* Played straight with the [[PortalNetwork Pandora gates]] in ''TabletopGame/EclipsePhase''. As they are [[SufficientlyAdvancedTechnology sufficiently advanced]], they use some sort of force field to keep the atmospheres on opposite sides of the portal from interacting.

* In ''{{Watchmen}}'', a superheroine has her mind wiped and is trapped in a marriage with an abusive and worthless husband. The friend who rescues her to restore her memory delivers an ultimatum to the "husband" who is in on the deception: walk through that door and disappear, and you'll never hear from us again. He walks, only to find, very briefly, he is at the bottom of the Pacific Ocean being crushed by thirty thousand feet of water. The transition between states is not detailed, nor is the mechanism that prevents six square miles of water under serious pressure suddenly gushing into a bedroom in the USA.
