Sentences with phrase «where atmospheric waves»

The location of the oscillation determines where atmospheric waves will form, and their eventual impact on say, California.

Not exact matches

The best way to explain this spike is from the swirling maelstrom below, where turbulent atmospheric waves must generate heat by crashing together like breakers on a windy beach shore.

Along the East Coast, where the «green wave» of spring leaves sprouting from maples, oaks and poplars historically has rolled from Miami to Maine in 75 days, atmospheric scientists with Princeton University predict the wave could take just 59 days by the end of the century.

Using her distinctive style of combining drawing, painting, collage and found objects, she has created atmospheric paintings that explore a world of waves, ice and whales; where in the summer, the sun never sets.

That happens to coincide with the region where the largest waves in the atmosphere (called Rossby waves) propagate, so therefore snow cover variability can have a direct impact and those waves, which dominate the large - scale atmospheric circulation.

Since 1998 ECMWF has been running a coupled forecasting system where the atmospheric component of the Integrated Forecasting System (IFS) communicates with the wave model (WAM) through exchange of the Charnock parameter which determines the roughness of the sea surface (Janssen, 2004).

The corresponding working quasilinear wave equation for the barotropic azonal stream function Ψm ′ of the forced waves with m = 6, 7, and 8 (m waves) with nonzero right - hand side (forcing + eddy friction) yields (34) u˜ ∂ ∂ x (∂ 2Ψm ′ ∂ x2 + ∂ 2Ψm ′ ∂ y2) + β˜ ∂ Ψm ′ ∂ x = 2Ω sin ϕ cos2 ϕT˜u˜ ∂ Tm ′ ∂ x − 2Ω sin ϕcos2 ϕHκu˜ ∂ hor, m ∂ x − (kha2 + kzH2)(∂ 2Ψm ′ ∂ x2 + ∂ 2Ψm ′ ∂ y2), [S3] where x = aλ and y = a ln -LSB-(1 + sin ϕ) / cos ϕ] are the coordinates of the Mercator projection of Earth's sphere, with λ as the longitude, H is the characteristic value of the atmospheric density vertical scale, T˜ is a constant reference temperature at the EBL, Tm ′ is the m component of azonal temperature at this level, u˜ = u ¯ / cos ϕ, κ is the ratio of the zonally averaged module of the geostrophic wind at the top of the PBL to that at the EBL (53), hor, m is the m component of the large - scale orography height, and kh and kz are the horizontal and vertical eddy diffusion coefficients.

The authors however believe a positive AO and NAO leads to atmospheric wave train patterns which may have delayed opposite effects — leading to a negative AO and NAO later on in the season — and that is where especially associated European cold spells would originate from.
