1 Convective generation of cirrus near the tropopause.

2 The whole tropical tropopause has been warmed up from cold period to warm period.

3 Tropopause folding and cut-off low in mid-latitude were well studied in the past.

4 Next comes the tropopause, which is the upper boundary of the troposphere.

5 The downward transport of ozone due to tropopause folding can reach middle part of troposphere, which has the most influence on the ozone in the upper troposphere.

6 The global variation characteristics of tropopause are shown by analyzing the data of temperature profiles from Radio Occultation(RO) observations aboard the satellites of COSMIC.

7 As soon as the tropopause is reached, temperature stops decreasing with height.

8 The tropopause folding, which means that high PV spreads downward from the upper troposphere or stratosphere, helps the releasing of potential instability energy and the development of rainstorm.

9 The relationship between arctic tropopause height and surface air temperature is discussed by using the aerological sounding and surface data during 1977-1990 in Beijing area.

10 The global distributions of tropopause height and temperature and their temporal variation depending on latitude, by using the method of Lapse Rate Tropopause (LRT), are discussed.

11 The frenqu-ency distribution of compound tropopause in summer and winter and inter-diurnal variation of various categories of tropopause over Beijing.

12 But the measurements show that these differences are small, for example only a few Kelvin at the tropopause.

13 Based on sounding data of 120 meteorological observation stations in China from 1980 to 2007, the height of tropopause, tropospheric temperature and temperature at low stratosphere were calculated.

14 Analysis of the observational data, the TOMS total ozone, and NCEP circulation,[www.Sentencedict.com] shows that the atmospheric ozone amount experienced a high-low-high variation with low-high-low tropopause altitude.

15 The line between the troposphere and the rest of the blue-colored atmosphere is called the tropopause.

16 Diagnostic Study of Jet Streaks: Kinematic Signatures and Relationship to Coherent Tropopause Disturbances.

17 Radiative forcing is defined as a change in average net radiation at the top of the troposphere ( tropopause ) due to a change in either solar or infrared radiation.

18 Strong westerlies, at times, have been observed near the tropopause over Recife, Brasil, approximately 9o from the equator.

19 The dominant periodicities as detected in the index of either pressure or temperature at tropopause are the 11 year and 3-5 years.

20 The largest differences are near the ground and in tropopause region, particularly over the land with complicated topography.

21 The troposphere is the layer from the earth's surface to the tropopause, which is at 10-15 km altitude depending on latitude and time of year. (Mt.

22 The results show that the H2O mixing ratio decreases with height in upper troposphere quickly reaches a minimum near the tropopause and the bottom of stratosphere; and then it increases .
