      Meteorologists generally define four seasons in many climatic areas: spring, summer, autumn (or fall) and winter. These are demarcated by the values of their average temperatures on a monthly basis, with each season lasting three months. The three warmest months are by definition summer, the three coldest months are winter, and the intervening gaps are spring and autumn. Spring, when defined in this manner, can start on different dates in different regions. In terms of complete months, in most North Temperate Zone locations, spring months are March, April and May although differences exist from country to country. (Summer is June, July, August; autumn is September, October, November; winter is December, January, February). The vast majority of South Temperate Zone locations will have opposing seasons with spring in September, October and November

      In the USA and some other regions in the Northern Hemisphere, the astronomical vernal equinox (currently around 20 or 21 March) is often taken to mark the first day of spring, and the summer solstice is sometimes taken as the first day of summer (usually 21 June in the Northern Hemisphere). In another US tradition, 2 February, Candlemas, can be regarded as the start of spring if it is mild (see Groundhog Day). In South Africa, Australia, and New Zealand, spring begins on 1 September, and has no relation to the vernal equinox. In Ireland spring traditionally starts on 1 February, St Brigid's Day

      In South America, the Tupi-Guarani calendar, from the former inhabitants of what is presently Brazil, Northern Argentina and Paraguay, counted 365 days, plus a fourth part of a day, needing no extra day every four years. The beginning of the solar year was marked by the rising of the M25 Constellation in the horizon, which occurs between June 5 and June 11 in this part of the world. For these native people, the four seasons were clearly identified by the solstices and equinoxes[citation needed]. The trajectory of the Sun throughout the year was divided into "The New Age" (Ara Pyau) and "The Old Age" (Ara Ymãwink. Ara Pyau was spring and summer, and Ara Ymã was autumn and winter. This calendar, which had no graphed or written form, marked activities such as hunting, fishing, planting, harvesting and religious rituals. In East Asian Solar term, spring begins on 4 February and ends on 5 May. Similarly, according to the Celtic tradition, which is based solely on daylight and the strength of the noon sun, spring begins in early February (near Imbolc or Candlemas) and continues until early May (Beltane). Swedish meteorologists define the beginning of spring as the first occasion on which the average daytime temperature exceeds zero degrees Celsius for seven consecutive days, thus the date varies with latitude and elevation. The phenological definition of spring relates to indicators, the blossoming of a range of plant species, and the activities of animals, or the special smell of soil that has reached the temperature for micro flora to flourish. It therefore varies according to the climate and according to the specific weather of a particular year.

      In spring, the axis of the Earth is increasing its tilt toward the Sun and the length of daylight rapidly increases for the relevant hemisphere. The hemisphere begins to warm significantly causing new plant growth to "spring forth," giving the season its name. Snow, if a normal part of winter, begins to melt, and streams swell with runoff. Frosts, if a normal part of winter, become less severe. In climates that have no snow and rare frosts, the air and ground temperature increases more rapidly. Many flowering plants bloom this time of year, in a long succession sometimes beginning even if snow is still on the ground, continuing into early summer. In normally snowless areas "spring" may begin as early as February (Northern Hemisphere) heralded by the blooming of deciduous magnolias, cherries, and quince, or August (Southern Hemisphere) in the same way. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, or monsoonal, or cyclonic. Often the cultures have locally defined names for seasons which have little equivalence to the terms originating in Europe. Many temperate areas have a dry spring, and wet autumn (fall), which brings about flowering in this season more consistent with the need for water as well as warmth. Subarctic areas may not experience "spring" at all until May or even June, or December in the outer Antarctic.
      While spring is a result of the warmth caused by the turning of the Earth's axis, the weather in many parts of the world is overlain by events which appear very erratic taken on a year-to-year basis. The rainfall in spring (or any season) follows trends more related to longer cycles or events created by ocean currents and ocean temperatures. Good and well-researched examples are the El Niño effect and the Southern Oscillation Index
      Unstable weather may more often occur during spring, when warm air begins on occasions to invade from lower latitudes, while cold air is still pushing on occasions from the Polar regions. Flooding is also most common in and near mountainous areas during this time of year because of snowmelt, accelerated by warm rains. In the United States, Tornado Alley is most active this time of year, especially since the Rocky Mountains prevent the surging hot and cold air masses from spreading eastward and instead force them into direct conflict. 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. Even more so than in winter, the jet streams play an important role in unstable and severe weather in the springtime in the Northern Hemisphere.
      In recent decades season creep has been observed, which means that many phenological signs of spring are occurring earlier in many regions by a couple of days per decade.
      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 the Prague Spring. Spring in the Southern Hemisphere is different in several significant ways to that of the Northern Hemisphere. This is because: there is no land bridge between Southern Hemisphere countries and the Antarctic zone capable of bringing in cold air without the temperature-mitigating effects of extensive tracts of water; the vastly greater amount of ocean in the Southern Hemisphere at all latitudes; at this time in Earth's geologic history the Earth has an orbit which brings it in closer to the Southern Hemisphere for its warmer seasons; there is a circumpolar flow of air (the roaring 40s and 50s) uninterrupted by large land masses; no equivalent jet streams; and the peculiarities of the reversing ocean currents in the Pacific.

      Le printemps (du latin primus, premier, et tempus, temps, cette saison marquant traditionnellement le renouveau dans la nature) est l'une des quatre saisons des zones tempérées, suivant l'hiver et précédant l'été. Cette demi-saison correspond aux mois de mars, avril, mai et juin dans l'hémisphère nord. Il se caractérise par un radoucissement du temps, la fonte des neiges, le bourgeonnement et la floraison des plantes, le réveil des animaux hibernants et le retour de certains animaux migrateurs.

      Du point de vue météorologique, dans l'hémisphère nord, le printemps est une demi-saison se situant entre la saison froide et la saison chaude. Il comprend donc les mois de mars, avril et mai. Dans l'hémisphère sud, ce découpage correspond à la saison d'automne.

      Dans le calendrier civil français, le printemps commence conventionnellement le 20 ou 21 mars, bien que cela ne corresponde ni au printemps astronomique, ni au printemps météorologique: en effet, le mois de mars dans son ensemble est en moyenne non seulement plus doux que les mois de décembre, janvier, et février, mais également, en règle générale, que celui de novembre, faisant de ce mois un mois typiquement printanier
      En Russie, le printemps débute le 1er mars, en conformité avec le printemps météorologique. En Australie et en Nouvelle-Zélande, le début du printemps officiel est le 1er septembre, en accord avec le printemps météorologique de l'hémisphère sud.
      Dans le calendrier iranien, le premier jour du printemps, norouz est resté le premier jour de l'année. La fête est célébrée par certaines communautés le 20 mars systématiquement, et par d'autres le jour de l'équinoxe vernal de l'hémisphère nord, qui a lieu le 20, 21 ou 22 mars.

      Le printemps est en zone tempérée la saison des giboulées. Il est caractérisé par une alternance de pluies et de journées ensoleillées, et de la fonte des neiges. Cette fonte survient plus rapidement en plaine qu'en montagne. Aussi il est fréquent que les habitations et les champs situés près des cours d'eau soient inondés durant la nouvelle saison en raison du sol gorgé d'eau. Aux États-Unis, en Nouvelle-Angleterre, le printemps est appelé «saison de la boue».
      Selon la durée et la rigueur des hivers dans les différents pays tempérés, on assiste (de mi-mars à fin avril et même en mai dans les pays à hiver rigoureux comme au Canada) à un réveil de la nature. Les arbres, dépouillés de leurs feuilles au cours de l'automne, revivent sous l'effet des températures clémentes, des pluies fréquentes et du soleil un peu plus présent que durant la mauvaise saison. La sève descendue dans le tronc des arbres remonte, les bourgeons, restés fermés durant tout l'hiver, s'ouvrent et de nouvelles feuilles d'un vert tendre font leur apparition, grandissent et s'élargissent jusqu'à atteindre leur taille normale selon l'espèce. Elles garderont cette taille mais seront d'un vert plus foncé durant l'été. C'est le moment où les oiseaux migrateurs reviennent et où ceux qui hivernaient se réveillent.
      Certains arbres fruitiers (pommiers, cerisiers...) signalent leur activité en premier lieu par l'apparition de fleurs (blanches, roses, mauves...), puis ces fleurs tombent ou sont emportées par le vent pour laisser place à de jeunes feuilles.
      Les prairies et les champs sont souvent recouverts de fleurs et d'une herbe jeune et neuve, un plaisir pour le bétail libéré de son régime au foin durant l'hiver.

      Dans la Rome antique, la déesse Flore personnifiait le printemps. Cette vision poétique des choses fut remise en honneur à la Renaissance dans tous les domaines artistiques : en poésie, en peinture (la célèbre Allégorie du Printemps de Botticelli), en sculpture (bas-relief le Printemps de Bouchardon) et en musique (Le Printemps dans les Quatre Saisons de Vivaldi).

      Весна́ — одно из четырёх времён года, между зимой и летом. Слово имеет древнюю индоевропейскую основу и сродни лит. vasarà — «лето», лтш. — pavasaris, др.-инд. vasantás — «весна», vasar — «рано». Весна — 02.03–31.05 (в високосные годы 01.03–31.05)

      Состоит из трёх месяцев: в северном полушарии — марта, апреля и мая, в Южном — сентября, октября и ноября. Весна — переходный сезон, когда заметно увеличение светового дня, повышается температура окружающей среды и активизируется природная деятельность живых существ и растений.

      В отличие от календа́рной, астрономическая весна наступает позже — во время весеннего равноденствия 20, 21 или 22 марта (в северном полушарииwink и 22, 23 сентября (в южном полушарииwink и продолжается до солнечнего солнцестояния (20 или 21 июня в северном полушарии и 21 или 22 декабря в южном полушарииwink.
      До XVIII века в Московском государстве весна отсчитывалась от Благовещения 25 марта до Рождества Иоанна Предтечи 24 июня. В каждом времени года считалось по 91 дню и по полчетверти часа.
