Foggy during winters

Winter season in Northern India sees the regular occurrence of fog, a natural phenomenon heightened by cooler temperatures

Fog is characterized by visibility often less than 1 km, which often occurs in the mornings between late October and early February

[{"selector":"#anim-97eb6524-99aa-4cbe-9632-4d257e54895b [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-33.043461933468514%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-9ff62b64-5ca7-4e67-b574-e9d36d4f80f2","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-3e0732b4-c6e0-4710-9369-c8fcdee87adb","keyframes":{"transform":["translate3d(0px, 149.37278%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

This is where the sun persists during the day, but temperatures sharply drop overnight, creating favorable conditions for fog

[{"selector":"#anim-919451d5-9a46-42ab-b6db-b8eb3dad98b2 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(43.14916480986296%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-2c24695f-8cad-408e-a18c-e883326194a4","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-400469a8-4002-4c78-abbb-2a65736d619b","keyframes":{"transform":["translate3d(0px, -542.92126%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

During cooler months, the sun evaporates water from morning dew, lakes, and rivers producing “invisible” water vapor

[{"selector":"#anim-21240c8e-30b2-4915-a1da-68e43df59827 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-35.537358435642965%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-9c6a6346-183a-4819-9913-26d328715768","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-fba62ea5-f012-4c16-9f6c-37d987dfbc87","keyframes":{"transform":["translate3d(0px, -542.11482%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

At night time, the air cools turning vapor into water droplets, which gather atmospheric dust and soot particles making visibility like fog

[{"selector":"#anim-630256b5-95cb-4129-8033-27935c60af35 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-32.34725425119907%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-8441d3ee-305e-42ea-9e0d-3ce19dfa6a78","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-7e38335e-a6ac-4a7f-9860-10702e6de7a1","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

The occurrence of fog is directly linked to a temperature change, larger variation causes denser fog

[{"selector":"#anim-00e74f0d-d4b9-4495-8407-787c3d2ef1b5 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-36.81502770647628%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-aab6de17-5c0e-4b01-9993-5efb814c55fe","keyframes":{"opacity":[1,1]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-40ee41df-9632-42ff-976c-371c67ac6843","keyframes":{"transform":["scale(3)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

Fog often shrouds the landscape during high-pressure systems in winter, when low wind speeds prevent its natural dispersion

[{"selector":"#anim-71f936aa-f054-41fe-a510-44d0abe02f10 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(30.434270179433305%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-4437f8e2-4750-48cb-af49-2bce9ae38caf","keyframes":[{"offset":0,"transform":"translate3d(0, -544.53419%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.29,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.45,"transform":"translate3d(0, -153.123014228%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.61,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.71,"transform":"translate3d(0, -52.057468564%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.8,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.85,"transform":"translate3d(0, -19.548777421%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.92,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.96,"transform":"translate3d(0, -8.494733363999998%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":1,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"}],"delay":0,"duration":600,"fill":"both"}]

Though mist and fog are visually similar, mist is thinner and lighter than fog, which is much thicker and denser

[{"selector":"#anim-52e5c9c0-7c0d-4fc4-9bf8-96f51c5089e8 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-41.66330446236095%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-b625d69c-98ed-4a78-ac91-0c85a4f23c65","keyframes":{"transform":["scale(1)","scale(1.5)","scale(0.95)","scale(1)"],"offset":[0,0.33,0.66,1]},"delay":0,"duration":1450,"easing":"ease-in-out","fill":"both","iterations":1}]

While Smog is formed by mixing air with pollutants and exhaust gases resulting from human activities
