Air pollution qualifies as such. Surrounding mountains and high elevation above sea level contribute to a "cook pot effect", preventing air currents from blowing the smog away, and keeping it trapped in the Mexico City valley below.
Hills and mountains qualify as such. Both Santiago and Mexico City are surrounded by these, which act as a barrier, preventing strong winds to dissipate the air pollution.
In Mexico City the last snowfall was on January 12, 1967. Nonetheless, in the surrounding mountains it can snow every year during the winter months, January and February most likely.

If driving south on highway 2 to highway 15 into Mexico City, you will pass through the Sierra Madre Mountains, which are also an extension of the Rocky Mountains.
Some of the landforms in the Aztec region include mountains, valleys, lakes, and volcanic terrain. The Valley of Mexico, where the capital city of Tenochtitlan was built, is a prominent landform with its surrounding mountains. The nearby Lake Texcoco and active volcanoes like Popocatepetl further shaped the landscape of the Aztec civilization.
No. Mexico city is within a valley, but it is not affected by any kind of rain-shadow effect.
Hills and mountains.
The city sits in a valley surrounded by mountains. Smog from manufacturing and chemical plants as well as vehicle exhaust fumes get trapped by the surrounding mountains due to lack of any powerful-enough winds. This makes up the layer of gloom that sits over the valley due to a "cook-pot effect".
Funny guy. Mexico City is surrounded by hills and mountains on both sides.
