摘要

摘要如今，垂直切变被认为是冰架应力平衡的一个重要组成部分。然而，第一个冰架模型是在忽略垂直剪切的基础上建立的。部分由于它的历史处理，它仍然普遍讨论垂直剪切，好像它仍然被认为是可以忽略不计的冰架模型。在这里，我们提供了垂直剪切随时间变化处理的历史视角，并强调了该术语在当前冰架模型中的不可忽略性。我们在一个解析的、等温的、浅冰架模型的最简单的背景下说明我们的讨论。

Brief communication: Is vertical shear in an ice shelf (still) negligible?

Abstract. Vertical shear is recognized today as a key component of the stress balance of ice shelves. However, the first ice shelf models were built on the neglect of vertical shear. Partly due to its historical treatment, it remains common to discuss vertical shear as though it were still considered negligible in ice shelf models. Here, we offer a historical perspective on the changing treatment of vertical shear over time, and we emphasize the term's non-negligibility in current ice shelf modeling. We illustrate our discussion in the simplest context of an analytic, isothermal, shallow-ice-shelf model.

期刊介绍： The Cryosphere (TC) is a not-for-profit international scientific journal dedicated to the publication and discussion of research articles, short communications, and review papers on all aspects of frozen water and ground on Earth and on other planetary bodies. The main subject areas are the following: ice sheets and glaciers; planetary ice bodies; permafrost and seasonally frozen ground; seasonal snow cover; sea ice; river and lake ice; remote sensing, numerical modelling, in situ and laboratory studies of the above and including studies of the interaction of the cryosphere with the rest of the climate system.
