Isotherms surface maps
A line connecting points of equal temperature is called an isotherm. That means, at every point along a given isotherm, the values of temperature are the same.

Isotherm - A line of constant temperature.
ITCZ - Inter-Tropical Convergence Zone. A region where the two equatorial Hadley cells border each other. Air converges near the equator associated with upward motion and divergence aloft.
Isotherm: A line connecting locations with the same temperature.
Jet stream: A narrow region of relatively strong winds (i.e., wind speeds greater than 70 knots) usually located in the upper troposphere.
Isotherm- the line of equal temperature denoted on surface weather maps.

January Thaw- a period of mild weather popularly supposed to recur each year in late January.
isotherm: a line passing through points of equal temperature on a map.
jet stream: narrow river of very strong horizontal winds usually located in the upper troposphere along fronts.
Isotherm A line on a weather map connecting points of equal temperature.
Isothermal Of equal or constant temperature with respect to either space or time.
Isotherm An isoline connecting all points of equal temperature.
Latent heat Heat energy is stored in one of three states- ice, water, or water vapor. The energy is absorbed or released in each phase change from one state to another.
ISOTHERM- A line of constant temperature.
JET STREAK- A relative maximum of windflow within the jet stream.
JET STREAM- The meandering belt of strong upper level winds that separates milder mid-latitude air from cold polar air.

isotherm—A line of equal or constant temperature.
isothermal—Of equal or constant temperature, with respect to either space or time; more commonly, temperature with height; a zero lapse rate.

In studying the tropical Pacific Ocean, the depth of 20ºC water ("the 20ºC isotherm") is often used as a proxy for the depth of the thermocline.
Polar JetMarked by a concentration of isotherms and strong vertical shear, this jet is the boundary between the polar air and the subtropical air.
isotherms and height contours are nearly parallel everywhere and directional wind shear is weak.
melting layerThe layer below the 0°C isotherm where snowflakes melt and turn into raindrops. When viewed by radar this layer appears as a band of enhanced reflectivity; thus it is commonly known as the "radar bright band.
Baroclinic Atmosphere:Isotherms move across the isobars or contours.
Barogram:A written record of the atmospheric pressure: (Graph)
Barograph:A weather instrument used to measure atmospheric pressure. It consists of an aneroid cell which ...
Isotherms, isotachs, etc. are all examples of isopleths.IsotachA line connecting points of equal wind speed.IsothermA line connecting points of equal temperature.
Isothermal or small lapse rate of temperature(positive or negative). Because of the temperature structure, very little overturning of air takes place, either within the stratosphere, ...
Isotherm A line of equal or constant temperature. Isothermal layer Atmospheric layer throughout which there is no change of temperature with height, i.e. a zero lapse rate.
In such systems, height contours and isotherms are parallel everywhere, and winds do not change direction with height.
As a rule, a true equivalent barotropic system can never be achieved in the real atmosphere.
Isotherms can be drawn like isobars, and the two sets of curves can have any relation to each other.
Marked by a concentration of isotherms and vertical shear, this jet is the boundary between the subtropical air and the tropical air. It is found approximately between 25° and 35° North latitude and usually above an altitude of 40,000 feet.
ISOTACH A line connecting equal wind speeds. ISOTHERM The line of equal or constant air temperature. If something is isothermal, it is of equal or constant temperature with respect to either time or space.

Latent heat The heat released or absorbed per unit mass by a system in a reversible isobaric-isothermal change of phase.
However, a shallow isothermal or relatively stable layer is more usual indication of a well-defined front. Frequently, the frontal boundary is so weak or distorted by other discontinuities that frontal identification is difficult.
no dissipation, isothermal atmosphere) do not correspond to conditions in the actual atmosphere. As a result, a numerical solution which takes these factors into account is often calculated using general circulation models and climate models.
A region of relatively cold air, represented on a weather map analysis as a relative minimum in temperature surrounded by closed isotherms.
Thus, it might be said that a surface pressure system tends to be steered by isotherms, contour lines, streamlines aloft, warm-sector isobars, the orientation of a warm front, etc.
Heat Island
Dome of warm polluted air which covers an urban area and in which the temperature is higher than in the surroundings. It appears as an "island" in the pattern of isotherms on a surface map.
meteorology, references to barotropic systems refer to equivalent barotropic systems - systems in which temperature gradients exist, but are parallel to height gradients on a constant pressure surface. In such systems, height contours and isotherms ...
For example, if the volume if halved, then the pressure is doubled. If the temperature is held constant, it becomes an isothermal process. Discovered by Robert Boyle (1627-1691), an Irish physicist and chemist and co-founder of the Royal Society.
For example, date palms grow only in regions where the mean temperature of the coldest month is greater than 18°C, so Köppen chose the 18°C isotherm in the coldest month as the boundary of the equatorial climate.
heat fluxes will cause larger changes in temperature in the valley volume than in the flat-floor volume.
