First Problem solution.

select id from
(
SELECT id,
case
when lag(Temperature) over(order by recordDate) < Temperature
and lag(recordDate) over (order by RecordDate) = recordDate - interval '1' day
THEN 1
ELSE 0 END SEL
FROM weather
)x
where sel = 1

Second Problem solution.

SELECT Id FROM
(
SELECT Id, (Temperature - LAG(Temperature) OVER (ORDER BY RecordDate)) as temp_diff,
       DATEDIFF(RecordDate, LAG(RecordDate) OVER (ORDER BY RecordDate)) as date_diff
FROM Weather
) as innerQ
WHERE temp_diff > 0 and date_diff = 1

Third Problem solution.

SELECT w.id FROM Weather w JOIN Weather p
ON w.recordDate = DATE_ADD(p.recordDate, INTERVAL 1 DAY) AND w.Temperature > p.Temperature
