Sentences with phrase «of air mass»

the el nino circulation is so clearly right on the equator... and discussion of air mass cells and oscillations and cyclones, and monsoons and jet streams — all this really needs to be animated to make sense.

More meridonal jet stream tracks flowing around the world between the climate zones result in longer lines of air mass mixing at climate zone boundaries.

When meridonal, the jet streams wander in loops further north and south, resulting in longer lines of air mass mixing at climate zone boundaries, which creates more clouds.

The jet streams are high - level rivers of fast moving air threading between the climate zones, and are driven by temperature, humidity and density differentials between the different types of air mass:

This relationship determines that in hydrostatic equilibrium any work — w ∂ pi / ∂ z performed by the vertical partial pressure gradient per unit time per unit atmospheric volume is compensated exactly by the work — wγiρg performed by the force of gravity that acts on a corresponding molar share γi of the air mass (here w is vertical velocity).

The reactivity and degree of water affinity of fog CCN become potentially even more complex when taking into account back trajectories of air masses over industrial and urban landscapes.

The latitudinal temperature gradient in summer is much smaller, thus providing less drive for exchange of air masses between middle latitudes and polar regions — and when exchange occurs the effect on temperature is less than that caused by a winter «polar express» of Arctic (or Antarctic) air delivered to middle latitudes.

You could divide up the geography into numerous cells, each with numerous layers of atmosphere; you could divide up the time into many small steps, and work out the dynamics of air masses in a refined way; you could make complex calculations of the transfer of radiation through the air; you could construct detailed models for surface effects such as evaporation and snow cover... but you could not do all these at once.
