The blue jay is a passerine bird in the family Corvidae, native to North America. It is resident through most of eastern and central United States, although western populations may be migratory. Resident populations are also found in Newfoundland, Canada, while breeding populations can be found in southern Canada. It breeds in both deciduous and coniferous forests, and is common near and in residential areas. It is predominantly blue with a white chest and underparts, and a blue crest. It has a
temperature gradient. At sea, a temperature gradient is the change of temperature with depth; a positive gradient is a temperature increase with an increase in depth, and a negative gradient is a temperature decrease with an increase in depth. Thesaurus AntonymsRelated WordsSynonymsLegend:
The rate of change is called the pressure gradient. Pressure gradient force is the force that moves air from an area of high pressure to an area of low pressure. The velocity of the wind depends upon the pressure gradient.If the pressure gradient is strong, the wind speed is high.herefore, a pressure gradient exists in the horizontal (along the surface) as well as the vertical plane (with altitude) in the atmosphere. HORIZONTAL PRESSURE GRADIENT. The horizontal pressure gradient is steep or strong when the isobars determining the pressure system (fig.
