Average sea level pressure has been getting higher in China, particularly in North China in winter.

中国海平面气压的变化总的来说是增大的，尤其是北方的冬季。

Eurasian winter sea level pressure anomalies during 1948-2007 were investigated by applying a nonlinear principal component analysis (NLPCA) method.

The results show that the calculations of typhoon sea level pressure field and wind field by means of advanced typhoon pressure models is desirable.

结果表明，改进后的台风气压模型对台风海面气压场和风场的模拟计算是可取的。

The air pressure in a plane during flight is lower than at sea level.

That will raise the sea level, increasing the pressure at the bottom and thus stabilising clathrates there in other words, there will be negative feedback.

"By that I mean try to imagine creating a cavity inside your mouth without any air bubbles and by letting in no air through your lips or throat -- it's basically impossible at sea level because the air pressure outside your mouth pushes the air pocket closed, " he said.

Fuelled by strong winds, if a surge coincides with low pressure, it could raise the sea level around eastern England by more than 2m.
