1)
To answer the question, "What kind of weather will we have (Future
Simple Active, мн. ч.) next
winter?" is (Present Simple Active, ед.ч.) an entirely different kind of problem from
saying what the weather will be (Future Simple Active, ед.ч.) like in
New York or Boston tomorrow or the next day.
2)
No one to date has demonstrated (Present Perfect Active, ед.ч.) ability to
forecast local day-to-day weather changes with any significant degree of skill
more than four or five days ahead.
3) We are working (Present Continuous
Active, мн. ч.) on the
solar-weather analogue approach to the preparation of a weather forecast for
the two or three seasons ahead.
4) For a long time to come, seasonal weather
forecasts will be based (Future Simple Passive, мн. ч.) on a
statistical or pattern analogy.
5) More distant conditions or physical factors
do not have (Present Simple Active, мн. ч.) time to make their influences felt within a
day or two.
6) It was (Past Simple Active, ед. ч.) we who
select the two or three analogue years which correspond best to the current
year in the large-scale weather patterns of the northern hemisphere.
7) The article said that we had (Past
Simple Active, мн. ч.) empirical
as opposed to scientific forecasting.
8) We have selected (Present Perfect
Active, мн. ч.) the two or
three analogue years which correspond best to the current year in the
large-scale weather patterns of the northern hemisphere.
