Exploring the Effects of Atmospheric Forcings on Evaporation: Experimental Integration of the Atmospheric Boundary Layer and Shallow Subsurface
Published on: June 8, 2015
Summary
The Mars atmosphere heats and cools rapidly, about 50 times faster than Earth's, leading to solar-controlled winds. Unstable eddies are common, except in Martian summer.
Area of Science:
- Planetary Science
- Atmospheric Science
- Mars Meteorology
Background:
- Earth's atmospheric response to surface temperature changes is well-understood.
- The Martian atmosphere's thermal dynamics and response times require further investigation.
Purpose of the Study:
- To analyze the response time of the Mars atmosphere to surface temperature changes.
- To investigate the factors influencing Martian atmospheric circulation and phenomena.
Main Methods:
- Analysis of radiative and convective heating processes in the Mars atmosphere.
- Comparison of atmospheric response times between Mars and Earth.
- Modeling of atmospheric dynamics, including latent heat release and mass flow.
Main Results:
- The Mars atmosphere responds to surface temperature changes on a timescale of approximately one day.
- This response is about 50 times faster than that of Earth's atmosphere.
- Martian wind distribution is primarily solar-controlled, with modifications from CO(2) condensation.
- Unstable eddies, similar to terrestrial cyclones, are predicted for most Martian seasons.
Conclusions:
- The rapid atmospheric response on Mars significantly influences its weather patterns.
- Solar control is a dominant factor in Martian wind distribution.
- Further theoretical work is needed to fully understand thermally driven tides on Mars.

Overview
01:15Torque Free Motion
The torque-free motion refers to the movement of a rigid body in space when no external torques are acting upon it. This type of motion can be observed in environments where there are no external forces or frictions, like in outer space. For example, a rotation of Mars in space is a torque-free motion. Mars is an axisymmetric object, meaning it has an axis of symmetry along which it rotates, designated as the z-axis. The rotating frame of reference is defined such that the center of mass of...
01:10Kepler's First Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.

01:19Escape Velocities of Gases
To escape the Earth's gravity, an object near the top of the atmosphere at an altitude of 100 km must travel away from Earth at 11.1 km/s. This speed is called the escape velocity. The temperature at which gas molecules attain the rms speed, which is equal to the escape velocity, can be estimated by using the equation for the average kinetic energy of the gas molecules. According to the kinetic theory of gas, the average kinetic energy of the gas molecules is proportional to its temperature.
01:20Momentum And Radiation Pressure
An object absorbing an electromagnetic wave would experience a force in the direction of propagation of the wave. This force occurs because electromagnetic waves contain and transport momentum. The force accounts for the wave's radiation pressure exerted on the object. Maxwell's prediction was confirmed in 1903 by Nichols and Hull by precisely measuring radiation pressures with a torsion balance. The measuring instrument had mirrors suspended from a fiber kept inside a glass container. Nichols...
01:18Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...
