Seasonal Behaviour of Atmospheric Pressure Oscillations

Naturevolume 214pages4344 (1967) | Download Citation



IT is well known that the atmospheric pressure at any given point does not remain constant in time and is subject to periodic and non-periodic fluctuations. Statistical analyses have been used to establish them and many investigations have been published. This communication reports the results of a spectral density analysis performed for the barometric pressure data at the Langmuir Laboratory (33° 59′ N., 107° 11′ W., elevation 3,320 m above mean sea level), a research facility of the New Mexico Institute of Mining and Technology, and at the Institute campus at Socorro (34° 4′ N., 106° 54′ W., elevation 1,410 m above mean sea level). The Langmuir Laboratory is on a summit ridge of the Magdalena Mountains and the campus is 27 km east in the Riogrande Valley. A comparison of the results of these two stations provides an interesting example of atmospheric behaviour in a “mountain–valley” situation.
