Spring is one of the four temperate seasons. Nature, in the broadest sense is equivalent to the natural world, physical universe, material world or material universe. The weather is a set of all the phenomena occurring in a given Atmosphere at a given Time. A season is one of the major divisions of the Year, generally based on yearly periodic changes in Weather. Summer is one of the four Temperate Seasons Summer marks the warmest time of year with the longest days Autumn (also known as fall in North American English) is one of the four Temperate Seasons Autumn marks the transition from Summer Winter is one of the four Seasons of Temperate zones Calculated astronomically, it begins on the Solstice and ends on the Equinox The Tropics are centered on the Equator and limited in Latitude by the Tropic of Cancer in the northern hemisphere at approximately 23°26' (23 The dry season is a term commonly used when describing the weather in the Tropics. A wet season or rainy season is a Season in which the average Rainfall in a region is significantly increased A storm is any disturbed state of an astronomical body's atmosphere, especially affecting its surface and strongly implying Severe weather. A tornado is a violent rotating column of air which is in contact with both the surface of the earth and a Cumulonimbus cloud or in rare cases the base of a Cumulus A tropical cyclone is a storm system characterized by a low pressure center and numerous Thunderstorms that produce strong winds and Flooding Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are a group of Cyclones defined as synoptic scale low A winter storm is an event in which the dominant varieties of precipitation are forms that only occur at cold Temperatures such as Snow or A blizzard is a severe Winter storm condition characterized by low Temperatures strong Winds and heavy blowing Snow Blizzards are formed when An ice storm is a type of Winter storm characterized by Freezing rain. In Meteorology, precipitation (also known as one class of hydrometeors, which are atmospheric water phenomena is any product of the condensation of atmospheric Fog is a cloud that is in contact with the ground Stratus clouds are usually the only clouds that touch the ground Drizzle (also called mizzle) is light precipitation consisting of liquid water drops smaller than that of Rain, and generally smaller than 0 Rain is Liquid precipitation. On Earth it is the condensation of atmospheric Water vapor into drops heavy enough to fall often making it to Freezing rain is a type of precipitation that begins as Snow at higher altitude falling from a Cloud towards earth melts completely on its way down while passing Ice pellets are a form of precipitation consisting of small Translucent ice balls Hail is a form of precipitation which consists of balls or irregular lumps of ice (hailstones "Snowfall" redirects here For other uses see Snow (disambiguation or Snowfall (disambiguation. Graupel (also called snow pellets) refers to precipitation that forms when supercooled Droplets of Water condense on a Snowflake forming This is a list of meteorology topics.

Dates
According to the astronomical definition, spring begins on March 21 and lasts until June 20, the vernal equinox in the northern hemisphere. Events 630 - Byzantine emperor Heraclius restores the True Cross to Jerusalem. Events 451 - Battle of Chalons: Flavius Aetius ' defeats Attila the Hun. An equinox is the event of the Sun passing over the Earth's equator in its annual cycle Northern Hemisphere is the half of a Planet that is North of the Equator —the word hemisphere literally means 'half ball' According to this definition, therefore, the traditional mid-summer's day is the first day of summer. The meteorological definition (used in order to express whether 'spring' has been hot or cold or wet, for example) has spring starting on March 1, since this is more in line with weather conditions thought to be typical of spring. A season is one of the major divisions of the Year, generally based on yearly periodic changes in Weather. Events 86 BC - Lucius Cornelius Sulla, at the head of a Roman Republic army enters in Athens, removing the Tyrant The phenological definition of spring relates to the blossoming of a range of plant species. Phenology is the study of the times of recurring natural phenomena It therefore varies according to the climate (as in 'Spring comes late to the north-east'). Calendars typically give the first, but the second and third are more in line with common use.
According to solar term, spring begins on February 4 and ends on May 4. A solar term is one of 24 points in traditional East Asian Lunisolar calendars that matches a particular astronomical event or signifies some natural phenomenon Events 211 - Roman Emperor Septimius Severus dies leaving the Roman Empire in the hands of his two quarrelsome sons Events 1256 - The Augustinian monastic order is constituted at the Lecceto Monastery when Pope Alexander IV
In the southern hemisphere, spring is generally accepted to begin on September 1 and last until November 30. Southern Hemisphere is the half of a Planet that is South of the Equator —the word hemisphere literally means 'half ball' Events 462 - Possible start of first Byzantine indiction cycle. Events 1700 - Battle of Narva — A Swedish army of 8500 men under Charles XII defeats
As in summer, the axis of the Earth is tilted toward the Sun and the length of daylight rapidly increases in the northern hemisphere. EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 The Sun (Sol is the Star at the center of the Solar System. The northern hemisphere begins to warm significantly causing new plant growth to "spring forth," giving the season its name. Snow begins to melt and streams swell with runoff and spring rains. "Snowfall" redirects here For other uses see Snow (disambiguation or Snowfall (disambiguation. Most flowering plants bloom this time of year, in a long succession sometimes beginning even when snow is still on the ground, and continuing into early summer. In normally snow less areas "spring" may begin as early as February during warmer years, with subtropical areas having very subtle differences, and tropical ones none at all. The subtropics are the zones of the Earth immediately north and south of the tropic zone which is bounded by the Tropic of Cancer and the Tropic of The Tropics are centered on the Equator and limited in Latitude by the Tropic of Cancer in the northern hemisphere at approximately 23°26' (23 Sub arctic areas may not experience "spring" at all until May or even June, or December in the outer Antarctic.
Severe weather most often occurs during the spring, when warm air begins to invade from lower latitudes while cold air is still pushing from the Polar Regions. Severe weather is any destructive weather phenomenon. The term is usually used to refer to severe thunderstorms and related phenomena such as Tornados Latitude, usually denoted symbolically by the Greek letter phi ( Φ) gives the location of a place on Earth (or other planetary body north or south of the Earth's polar regions are the areas of the globe surrounding the poles also known as frigid zones. Flooding is also most common in and near mountainous areas during this time of year because of snowmelt, many times accelerated by warm rains. In the United States, Tornado Alley is most active by far this time of year, especially since the Rocky Mountains prevent the surging hot and cold air masses from spreading eastward and instead force them directly at each other. The United States of America —commonly referred to as the For the book by William S Burroughs, see Tornado Alley (book. Mountain peaks of the Rocky Mountains The Rocky Mountains, often called the Rockies, are a Mountain range in western North America. Besides tornadoes, supercell thunderstorms can also produce dangerously large hail and very high winds, for which a severe thunderstorm warning or tornado warning is usually issued. A tornado is a violent rotating column of air which is in contact with both the surface of the earth and a Cumulonimbus cloud or in rare cases the base of a Cumulus A supercell is a severe thunderstorm with a deep continuously rotating updraft (a Mesocyclone) Hail is a form of precipitation which consists of balls or irregular lumps of ice (hailstones See Severe weather terminology for a comprehensive article on this term and related weather terms A tornado warning is an alert issued by government weather services to warn an area that a Tornado may be Imminent. Even more so than winter, the jet streams play an important role in severe weather in the springtime. Jet streams are fast flowing relatively narrow air currents found at the Tropopause, the transition between the Troposphere (where temperature decreases
The hurricane season officially begins in late spring, on May 15 in the northeastern Pacific and June 1 in the northern Atlantic. A tropical cyclone is a storm system characterized by a low pressure center and numerous Thunderstorms that produce strong winds and Flooding Events 1252 - Pope Innocent IV issues the Papal bull Ad exstirpanda, which authorizes but also limits the The Pacific Ocean is the largest of the Earth 's Oceanic divisions Events 193 - Roman Emperor Didius Julianus is Assassinated 987 - Hugh Capet is elected Before these dates, hurricanes are almost unheard of and even tropical storms are rare, one of the earliest ever being Tropical Storm Ana in mid-April 2003. Tropical Storm Ana was the only Tropical cyclone on record in the Atlantic basin during the month of April
Spring is seen as a time of growth, renewal, of new life (both plant and animal) being born. The term is also used more generally as a metaphor for the start of better times, as in Prague Spring. The Prague Spring ( Czech: Pražské jaro, Slovak: Pražská jar) was a period of political liberalization in Czechoslovakia during
Nowruz
The first day of spring is the beginning of the new year, Nowruz, in the Iranian calendar.
