APAKAH MAKSUD LEE WAVE dalam CORSICA?
Gelombang Lee
Dalam meteorologi, gelombang lee adalah gelombang berdiri atmosfera. Bentuk yang paling umum ialah gelombang gunung, yang merupakan gelombang graviti dalaman atmosfera. Ini ditemui pada tahun 1933 oleh dua juruterbang glider Jerman, Hans Deutschmann dan Wolf Hirth, di atas Krkonoše. Mereka adalah perubahan berkala tekanan atmosfera, suhu dan ketinggian orthometric dalam arus udara yang disebabkan oleh anjakan menegak, contohnya angkat orografik apabila angin bertiup di atas gunung atau gunung. Mereka juga boleh disebabkan oleh angin permukaan yang bertiup di atas kerikil atau dataran tinggi, atau bahkan oleh angin atas yang dibelakang melalui jalan raya haba atau awan. Daya gerakan menegak berubah secara berkala dalam kelajuan dan arah udara dalam arus udara ini. Mereka sentiasa berlaku dalam kumpulan di bahagian lee di kawasan yang memicu mereka. Biasanya vorteks bergelora, dengan paksi putaran selari dengan julat gunung, dihasilkan di sekitar palung pertama; ini dipanggil pemutar. Gelombang lee terkuat dihasilkan apabila kadar luput menunjukkan lapisan stabil di atas halangan, dengan lapisan yang tidak stabil di atas dan di bawah.

Storm and Cloud Dynamics
By applying the wave equation to each separate layer, he found probably the
most important dynamic requisite for periodic lee-wave development, namely,
that l2 must be less in an upper layer than in a lower layer of sufficient depth. This
can ...

By discretizing (3.21) the resonant wavemodes can be sought and the linear
trapped lee wave solutions can then be computed (e.g. Sawyer 1960; Vergeiner
1971). For three-dimensional flows the resonant wavemodes will in general lie
along ...

Note that (5.5.14) is equivalent to (5.5.8) of the baroclinic lee wave theory except
that the streamfunction is used. Assuming y(t, x, y, z)1⁄4 (x, y, z)eÀiot and applying
the Fourier series expansion to the above system reduces it to an eigenvalue ...
