atmospheric tide meaning in Hindi

Examples

1. ii ) Atmospheric tides propagate in an atmosphere where density varies significantly with height.
2. Atmospheric tides can be measured as regular fluctuations in wind, temperature, density and pressure.
3. Although atmospheric tides share much in common with ocean tides they have two key distinguishing features:
4. Atmospheric pressure shows a diurnal or semidiurnal ( twice-daily ) cycle caused by global atmospheric tides.
5. Similarly, atmospheric tides arise from, for example, non-uniform solar heating associated with diurnal motion.
6. Atmospheric tides dominate the dynamics of the mesosphere and lower thermosphere, essential to understanding the atmosphere as a whole.
7. Lindzen's work on atmospheric tides led him to the study of planetary waves and the general circulation of atmospheres.
8. At ground level, atmospheric tides can be detected as regular but small oscillations in surface pressure with periods of 24 and 12 hours.
9. This led to their joint publication in 1969 of a 186-page monograph ( republished in 1970 as a book ) " Atmospheric Tides ".
10. i ) Atmospheric tides are primarily excited by the Sun's heating of the atmosphere whereas ocean tides are primarily excited by the Moon's gravitational field.
