  • The Gas Laws and the Weather
    IMPACT 1 ON ENVIRONMENTAL SCIENCE The gas laws and the weather The biggest sample of gas readily accessible to us is the atmos- 24 phere, a mixture of gases with the composition summarized in Table 1. The composition is maintained moderately constant by diffusion and convection (winds, particularly the local turbu- 18 lence called eddies) but the pressure and temperature vary with /km altitude and with the local conditions, particularly in the tropo- h sphere (the ‘sphere of change’), the layer extending up to about 11 km. 12 In the troposphere the average temperature is 15 °C at sea level, falling to −57 °C at the bottom of the tropopause at 11 km. This Altitude, variation is much less pronounced when expressed on the Kelvin 6 scale, ranging from 288 K to 216 K, an average of 268 K. If we suppose that the temperature has its average value all the way up to the tropopause, then the pressure varies with altitude, h, 0 according to the barometric formula: 0 0.5 1 Pressure, p/p0 −h/H p = p0e Fig. 1 The variation of atmospheric pressure with altitude, as predicted by where p0 is the pressure at sea level and H is a constant approxi- the barometric formula and as suggested by the ‘US Standard Atmosphere’, mately equal to 8 km.

    Mathematical Methods for Physicists, FK7048, fall 2019 Exercise sheet 1, due Tuesday september 10th, 15:00 Total amount of points: 12p, and 2 bonus points (2bp). 1 Barometric formula Hydrostatics is governed by the following equation: −! − r P + ρ ~g = ~0 (1) where ~g is the gravitational acceleration, assumed constant, P and ρ are the pressure and density fields. A barotropic fluid is a fluid whose density depends only on pressure viz. ρ = ρ(P ). (a) (1p) The earth's atmosphere can be considered in a first approximation as a barotropic fluid at equilibrium in the gravitational field ~g. Find an integral relation from which the evolution of the pressure as a function of altitude z for any given relation ρ(P ) can be obtained. Consider only the vertical direction and do not forget to set the initial condition. (b) (1p) Find the relation ρ(P ) for an ideal gas, starting from the usual equation of states (that is, the ideal gas las). Any parameter you may need to introduce will be considered constant so far. (c) (1p+1bp) Use the expression ρ(P ) for an ideal gas in your solution of question (a) to find P (z). − z You should obtain the so-called barometric formula P (z) = P0 e h . Give the analytical expression for h. Bonus: obtain a numerical value for h. Use your physical intuition to evaluate the parameters you have introduced in question (b). Is the answer you obtain resonable? (d) (1p) So far we have assumed that Earth's atmosphere is isothermal, however the temperature lapse rate is clearly non-negligible on the kilometer scale.

The first step of the scientific process is to ask a question. In this case, the question is: is barometric pressure different between stations? Start making observations by going to School2School.net, and clicking on the “Stations” tab. Navigate to your school’s station if you have your own TAHMO station, or else just choose a close station. Pick the Barometric Pressure icon (third from the left) to display the graph of the recorded pressures (See image below). Note the maximum, minimum, and average pressure values (using estimations is okay- just a rough guess by eye is appropriate). Choose another station and compare your results, do you see a difference in the range of pressures for different stations? [Answer: the maximum pressure recorded is different

  • Barometric Pressure Information Understanding How Barometric Pressure Affects a Refrigeration Thermostat
    Barometric Pressure Information Understanding how Barometric Pressure affects a refrigeration thermostat Introduction Barometric Pressure also known as atmospheric pressure is the force per unit area exerted against a surface by the weight of air above that surface in the Earth’s atmosphere. In most circumstances atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. The barometric pressure depends on other factors like earth location (earth is not round), weather conditions (air humidity, air temperature, air speed) and even the sea level. The barometric pressure is measured by a barometer (meteorological instrument that normally uses mercury for measurement, due to which we have the pressure unit Barometric pressure “mmHg”). Filling media (gas) As barometric (atmospheric) pressure is everywhere it will pressure inside bellows also surround the thermostat (outside and also inside). element according to the temperature. All refrigeration thermostats filled with superheated vapour have the same basic concept which is to transform temperature into pressure and then convert this pressure into force in order to open and close contacts. This means that the filling media pressure (gas) has to overcome the barometric pressure, meaning that the final pressure is the difference between the filling media pressure and barometric pressure. The final temperature changes if the barometric pressure also changes. Final pressure is the pressure difference All working temperatures are always specified at one barometric pressure (customer request). If the barometric pressure changes or it is different from that specified, the temperature also changes. This occurs for all vapour filled thermostats in the world.

In a short introduction the basic methods used in aviation for altitude determination are nominated, and the importance of the barometric altitude is pointed. Further, the atmosphere stratification is presented and the general differential equation, which gives the dependence of the static pressure by the altitude, is deduced. The barometric and the hypsometric formulas for the first four atmospheric layers are developed both in the analytical and numerical forms. Also, the paper presents a method to determinate the density altitude with an electronic flight instrument system. A brief review of the flight altitudes is performed, and the calculus relations of the density altitude are developed. The first two atmospheric layers (0÷11 Km and 11÷20 Km) are considered. For different indicated barometric altitudes an evaluation of the density altitude, as a function of non-standards temperature variations and of dew point value, is realized.

Daidzic: On Atmospheric Lapse Rates Horizontal and vertical flow in atmosphere and cloud formation and dissipation is of fundamental importance for meteorologists, climatologists, weather forecasters, geophysicists and other related professions. The cloud coverage also regulates terrestrial albedo, which significantly regulates energy balance of the Earth. Vertical motion of air, temperature distribution and formation of clouds is also of essential importance to air transportation and flying in general. Strong updrafts, low visibility, turbulence, wind-shear and many other hazardous effects are tied to vertical motion of moist air and thus critical to pilots, dispatchers, operators, and ATC. Atmospheric lapse rate (ALR) is a central ingredient in vertical stability of air and generation of clouds with extensive vertical development. Cumulonimbus clouds (CB) are the principal generators of severe weather and most flying hazards.

  • Calculating the Vertical Column Density of O4 from Surface Values Of
    https://doi.org/10.5194/amt-2021-213 Preprint. Discussion started: 26 July 2021 c Author(s) 2021. CC BY 4.0 License. Calculating the vertical column density of O4 from surface values of pressure, temperature and relative humidity Steffen Beirle1, Christian Borger1, Steffen Dörner1, Vinod Kumar1, and Thomas Wagner1 1Max-Planck-Institut für Chemie Correspondence: Steffen Beirle ([email protected]) Abstract. We present a formalism that relates the vertical column density (VCD) of the oxygen collision complex O2-O2 (denoted as O4 below) to surface (2 m) values of temperature and pressure, based on physical laws. In addition, we propose an empirical modification which also accounts for surface relative humidity (RH). This allows for simple and quick calculation of the O4 VCD without the need for constructing full vertical profiles. The parameterization reproduces the real O4 VCD, as 5 derived from vertically integrated profiles, within 0.9% 1.0% for WRF simulations around Germany, 0.1% 1.2% for − ± ± global reanalysis data (ERA5), and 0.4% 1.4% for GRUAN radiosonde measurements around the world. When applied − ± to measured surface values, uncertainties of 1 K, 1 hPa, and 16% for temperature, pressure, and RH correspond to relative uncertainties of the O4 VCD of 0.3%, 0.2%, and 1%, respectively. The proposed parameterization thus provides a simple and accurate formula for the calculation of the O4 VCD which is expected to be useful in particular for MAX-DOAS applications. 10 1 Introduction In the atmosphere, two oxygen molecules can build collision pairs and dimers, which are often denoted as O4 (Greenblatt et al., 1990; Thalman and Volkamer, 2013, and references therein).
