In Australia, the seasons are defined by grouping the calendar months in the following way: ...
Solar Seasons: A division of the year for non-tropical latitudes into four three-month periods based on the daylength or amount of potential solar radiation.
Seasons - The earth's position in relation to the sun is always changing. The earth spins around its axis, an imaginary line that runs between the north and south poles.
Growing Seasons
Generally, the period of the year during which the temperature of cultivated vegetation (i.e., the temperature of the vegetal microclimate) remains sufficiently high to allow plant growth.
The cycle of seasons in the polar and temperate zones of one hemisphere is opposite to that in the other.
PACPacificPacific Decadal Oscillation(Abbrev. PDO) - a recently described pattern of climate variation similar to ENSO though on a timescale of decades and not seasons.
TEMPERATE CLIMATE Climates with distinct winter and summer seasons, typical of regions found between the Tropics of Cancer and Capricorn and the Arctic and Antarctic Circles. Considered the climate of the middle latitudes.
For example, a long-range forecaster predicting conditions for the upcoming winter may make comparisons to analog seasons in which meteorological factors were similar to those of the upcoming season.
Often, monthly averaged data are grouped into seasons, according to the prescribed definition. sea surface temperature The temperature of the layer of seawater (approximately 0.5 m deep) nearest the atmosphere.
A recently described pattern of climate variation similar to ENSO though on a timescale of decades and not seasons.
Hurricane and Typhoon Seasons Severe tropical cyclones (wind speeds greater than 74 mph) are called hurricanes in the central and eastern Pacific, Gulf of Mexico and north Atlantic Oceans, typhoons in the western Pacific and Indian Oceans, ...
The seasons are attributed to this tilt as the earth orbits the sun. In winter the Northern Hemisphere is tilted away from the sun. there- fore, the nighttime hours are longer than the daytime hours.
Hurricanes also occur in the Arabian Sea and the Gulf of Bengal, where there are two hurricane seasons a year, corresponding with the monsoons.
It is the oblique orientation of the earth's axis relative to its orbit that accounts for the seasons, for, in the period of a year, the angle of incidence of incoming solar radiation varies by nearly 47° at any one place.
These regions have vague seasons except for near the lower latitudes. Often there is 24 hour sunlight or 24 hour night seasons depending on the time of the year. Weather is often cold and dry throughout the entire year.
Revolution determines the seasons, and the length of the year. In addition, differences in seasons occur because of Earth's inclination (tilt on its axis) of about 23.5 degrees as it revolves around the sun. Compare with rotation.
Land-breeze circulations can occur at any time of year, but are most common during the fall and winter seasons when water temperatures are still fairly warm and nights are cool.
Antarctic Air: Mass of air originating in the Antarctic Continent. It is cold and dry in all seasons of the year.
Watch the weather forecast on television or read the weather map in the newspaper. Save the maps for a month or more. You can see changes over time and compare conditions over several weeks and seasons.
[ This well produced magazine contains articles covering the full range of the meteorological science, from 'case-studies' of single events, through reviews of notable months/seasons in recent and long-past history, ...
It has come to be used as a term for abnormal warming events which occur, on an average of two or three times a decade and typically last for a few seasons. It has important consequenses to climate as well as for ocean states (fishing etc).
With so many different geographical regions across the state, it can get confusing very quickly as to where certain features are and how they affect the weather. This is more typical in the snow seasons where winter storms often are heavily ...
The CPC issues the ENSO Diagnostic Discussion around the middle of the month. The discussion addresses the current oceanic and atmospheric conditions in the Pacific and the seasonal climate outlook for the following one to three seasons.

Intertropical Convergence Zone (ITCZ): belt of clouds and thunderstorms that runs parallel to the equator and marks where the trade winds of both hemispheres come together. Shifts seasonally, and is associated with monsoons and dry seasons in ...
rises during the day, relative humidity goes down because the moisture capacity of the air increases
as temperature falls overnight, relative humidty goes up because the moisture capcity of the air decreases
this pattern holds for all seasons ...
The tropical year, also called the mean solar year, is dependent on the seasons. It is the interval between two consecutive returns of the sun to the vernal equinox.
The model got a very good test of its skill during its first year of operation in the hurricane season of 1995, which was one of the most active hurricane seasons in history.
The discussion addresses the current oceanic and atmospheric conditions in the Pacific and the seasonal climate outlook for the following one to three seasons.
Monsoon A seasonal wind of persistent direction, characterized by a pronounced change in direction between seasons.
