### natural phenomenon | physical phenomenon:

Inversion
* are abnormalities
  - an important generator of wind across the continental interior
  - books
  - chemical processes
  - common in insects
  - conformal
  - motion
  - mutation
  - variation
  - weather conditions that trap industrial emissions in valley areas
* can occur at almost any altitude
  - the surface or aloft in the atmosphere
* cause partial sterility.
* develop in the tropics when subtropical high pressure systems produce sinking air.
* form at night as cool air pools in lower elevations while the air aloft remains warm.
* happen as cold air drains down mountainsides to pool in the valleys.
* have the classic double loop at meiosis, and have no crossovers when heterozygotes.
* health promoting technique whose benefits have been well accepted for centuries.
* helps drain the liver of accumulated venous blood
  - to gently stretch muscles and ligaments
* is an easier way to reverse gravity and is decompressive
  - especially intense over water and can instantly degrade visibility to zero
  - more common under high pressure with clear skies and light winds
* is the action of turning the sole of the foot inward, towards the opposite foot
  - modus operandi of the socialist, the devil's disciple
  - to denial what jet fuel is to an air war
  - why West Yellowstone is often the coldest spot in the nation in winter
* means another location for a chord, and different finger positions.
* normally occur at dawn, dusk, or night.
* occur in the atmosphere all the time and are responsible for a variety of weather.
* occur when a large chunk of DNA gets turned upside down on the chromosome
  - stretch of DNA on the chromosomebecomes reversed in direction
  - cold stable air layers form above warmer air
* play an important role in determining cloud forms, precipitation, and visibility.
* preserve angles.
* procedure that flips the magnitudes about a pivot point.
* promote a feeling of lightness in the organs at once.
* recruits gravity's help in getting more blood to the brain.
* refers to the randomised exchange of alleles in chromosomes.
* relaxes and stretched tensed up muscles and adds to flexibility and lubrication of joints.
* restrict vertical air circulation.
* tend to dissipate during the middle of the day when wind currents mix the air layers.
* trap a dense layer of cold air under a layer of warm air.

### natural phenomenon | physical phenomenon | inversion:

Temperature inversion
* are a result of other weather conditions in an area
  - where air at the surface is cooler than the air above
* can enhance the severity of a photochemical smog episode
  - notoriously result in freezing rain in cold climates
* limit or prevent the vertical mixing of air.
* occur most frequently along coastal areas bordering large bodies of water
  - when warm air forms a cap above cool, stable air
* tend to trap air pollution near the surface.

Thermal inversion
* act like a lid over the basin.
* can trap pollutants close to the ground.

### natural phenomenon | physical phenomenon:

Meteor shower
* All meteor showers have their own radiant.
* Most meteor showers are active between midnight and dawn
  - spawned by comets
  - happen when Earth crosses the orbit of a comet
  - have their origins with comets
* Most meteor showers occur when a large asteroid falls to the earth
  - the earth passes through the debris tail left behind by a comet
  - result from debris that that boils off a comet when it passes close to the sun
  - take place when the Earth passes through the debris left behind by a comet
* Some meteor showers produce about the same rate of meteors around the same date every year.

### natural phenomenon | physical phenomenon | optical phenomenon:

Interference fringe
* formed by the etalon are conjugate with the sky.
* is an optical phenomenon
* show the magnitude and the location of localized deformation.
