1. It was found that on light clays, no-till planting may begin 1—2dayss sooner after rain than conventional planting.
2. Even in such a system, gross statistical divergence of two nearly identical initial states will occur, sometimes in a week.
3. As far back as 1920s attention was directed towards the problem.
4. First comes a gradual change in water level, the forerunner, a few hours ahead of the storm’s arrival.
5. Prior to the 1960s knowledge of the atmosphere above about 30 km was based largely on inferences from ground-based observations.
6. Even today, specific forecasts are only made for the period of 3 to 5 days in advance.
7. The 500-hPa height field shows a well-developed blocking high over the Gulf of Alaska, which lasts another seven days.
8. Such averages are usually taken over a period of time, such as an hour, a day, a month, or a year.
9. The experiment was conducted in the summer of 1977.
10. In early spring when temperature is too low to favor the growth and development of the plants so that they have to remain in the greenhouse.
11. During periods of light winds or reduced river flow coastal current often become so weak as to be barely discernible.
12. During the 19th century, the theories of tidal and acoustic gravity oscillations were subjects of great interest.
13. How often observations are made, and how widely they are spaced, depend on the scale of the atmospheric events about which information is desired.
14. Periods of precipitation are referred to as the “active” monsoon, and the lulls in between are called monsoon “break”.
15. Such currents may form, disappear, or change flow direction within a matter of hours or days.
16. The weather will be hot and dry from now on till the end of August for this region.
17. Spring tides occur every two weeks, usually within a few days of the new and full moon.
18. These vortices developed within 30 minutes or so of each other.
19. In a time-sharing system, it is very important that each user get a share of the CPU at regular intervals.
20. These stations may report weather intervals of an hour or even less to warn of approaching weather dangers.
21. Plants were measured for height of the tallest leaf at monthly intervals from May to September.
22. The dataset consists of twice daily 500-hPa height analyses from the U.S. National Meteorological Center for the 20 winters 1962/1963 through 1981/1982.
23. The observation was made at 0630 local time, February 15, 1984.
24. The project will be completed by mid-December.
25. There appears small high in the west on day 10.
26. The observation was carried out one month less two days.
27. In the meantime the sky is turning clear.
28. It rains more often than not during this season.
29. These circulation anomalies have long been recognized.
30. This plot will be prepared sometime next month.
31. It takes 23 hours, 56 minutes and 4 and a fraction of a second for the earth to complete one rotation.
32. For the 24—hour period following 1300 February 14, air temperature dropped 4.6℃.
33. The past decade has been a rapid expansion of our empirical knowledge of the observed circulation anomalies.
34. The day of the onset of blocking is defined as day zero, and the time is then measured relative to this day zero, thus, day -2 represents the time of two day prior to the onset; day +2 two days subsequent.
