Carnival In some regions,[ which? Meteorological reckoning[ edit ] Meteorologists generally define four seasons in many climatic areas: Spring, when defined in this manner, can start on different dates in different regions. In other traditions, the equinox is taken as mid-spring. Most ecologists divide the year into six seasons that have no fixed dates.
In Persian culture the first day of spring is the first day of the first month called Farvardin which begins on 20 or 21 March.
Flooding is also most common in and near mountainous areas during this time of year, because of snow-melt which is accelerated by warm rains.
Spring in the Southern Hemisphere is different in several significant ways to that of the Northern Hemisphere for several reasons, including: In addition to spring, ecological reckoning identifies an earlier separate prevernal early or pre-spring season between the hibernal winter and vernal spring seasons.
In climates that have no snow, and rare frosts, air and ground temperatures increase more rapidly. In North America, Tornado Alley is most active at 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.

The phenological or ecological definition of spring relates to biological indicators, such as the blossoming of a range of plant species, the activities of animals, and the special smell of soil that has reached the temperature for micro flora to flourish. Ecological reckoning[ edit ] The beginning of spring is not always determined by fixed calendar dates.
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. Subarctic areas may not experience "spring" at all until May.

Many flowering plants bloom at this time of year, in a long succession, sometimes beginning when snow is still on the ground and continuing into early summer. These indicators, along with the beginning of spring, vary according to the local climate and according to the specific weather of a particular year.
The three warmest months are by definition summer, the three coldest months are winter and the intervening gaps are spring and autumn. Unstable spring weather may occur more often when warm air begins to invade from lower latitudeswhile cold air is still pushing from the Polar regions.
Besides tornadoessupercell 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 Northern Hemisphere weather in springtime. The hemisphere begins to warm significantly, causing new plant growth to "spring forth," giving the season its name.Spring is the season of new beginnings.

It is generally defined in the Northern Hemisphere as extending from the vernal equinox (day and night equal in length), March 20 or 21, to the summer solstice (year’s longest day), June.
Meteorological reckoning. Meteorologists generally define four seasons in many climatic areas: spring, summer, autumn (fall) and winter.
These are demarcated by the values of their average temperatures on a monthly basis, with each season lasting three months. Seasons are periods in a year marked by specific weather conditions, temperatures and length of day.
Most modern day calendars divide the year in 4 seasons: spring, summer, fall (autumn) and winter. Spring season on the farm features pre-picked and u-pick sweet strawberries, a musical hayride, kids activities, school tours, group tours.Download
