Sentences with phrase «with tmax»

Otherwise, how can a chip with a Tmax of 150C ignite a match, or burn a «pit» in a CD?

Tmin has a similar story, with not much in common with Tmax once the sun sets.

Not exact matches

There has certainly been none at Oxford, with mean annual Tmax on a down trend of -0.07 oC p.a. since 1958, while Heathrow, only about 40 miles away does show a rising trend of 0.034 oC p.a. which obviously could not possibly have anything to do with the explosive growth of air traffic there since 1958.

Now since we were on CO2 correlation, would you expect CO2 to have a higher correlation with ERSSTv4, BEST Tmax or BEST Tmin?

That fluctuation is amplified by land surface temperatures in the same latitude band of about the same area, because the land surface temperatures are at a higher average altitude with a lower average specific heat capacity and the (Tmax + Tmin) / 2 method of determining «average» amplifies the variance.

3) The number of days over the top 10 % of highest TMax as an anomaly using 19 stations with records back before 1920.

It is important to be careful because in the 1940s, the stations with lower DTRs often had lower TMAXs possibly due to urban pollution (wood burning or else...).

On the other hand, if one can not take the watts from the sun and compute TMAX at the sensor for relativly Idealized site with any reliability....

After looking at 100 year long daily records of Tmin and Tmax for a bunch of sites, it seemed pretty clear to me that we could do with one measure.

Only one site went with the trend of Tmax «$» Tmin increasing with average wind velocity that would be suggested by Parker's assumptions and that was for the Alert, NU Canada site.

Temp being linear with the 4th root of the energy flux, a simply average of Tmax and Tmin doesn't yield the same number as averaging the 4th root.

As experiment 4 clearly shows surface Tmax is the driving factor in a deep atmosphere with a pressure gradient in a gravity field.

At Tmax, for example, there has been a steady T rise as the sun moves higher in the sky, the rise helped by convection of air with hot packets in it surrounding the site, held back if frost has formed overnight, complicated if there is snow around and water phase change effects need consideration, hindered or lagged by the thermal inertia of the screen surrounding the thermometer as the screen heats up.

For an atmosphere in a gravity field with a vertical pressure gradient in which the gases are free to move, the gas temperature set by surface conduction will be close to surface Tmax, not Tav.

The altitude where the radiation to the cosmos takes place with the associated cooling of the top of the air is near t = 1 from the top of the air, that is at a pressure (1 / tmax H2O)(1/4.5) or (1 / tmax CO2)(1/1.45); the line by line computation of figure 6 - C is a morphing from figure 6 - A.

I fear we are throwing away a lot of variance by starting with monthly Tavg or Tmean and ignoring the variance that comes from the (Tmax - Tmin) / 2 mean std error.

So dUHI is (usually) affecting tmin much more than tmax (and tmean) and we are looking for stations with small dUHI over time.

The first result would probably be a histogramm of raw data trends for stations wie equal trends in tmin, tmax, tmean compared with the others.

If the number of such stations is not sufficient, more stations may be added, by extracting only time spans with similar tmin, tmax, tmean.

Figure 23 is impressive as well, tmin tmax and tmean with identical -LRB-!)

4th Conclusion not supported with data in Section 3.2; specifically the conclusion «Additionally, it was observed that the Tmax trends of compliant CRS stations was significantly higher, suggesting that maintenance issues, such as paint deterioration over time...».

Manfred says: July 29, 2012 at 1:06 pm Figure 23 is impressive as well, tmin tmax and tmean with identical -LRB-!)

(2010) did this with the homogenized data from different subsets of stations, and found very strong correlations with the entire USHCN dataset (r2 = 0.98 for Tmax, and r2 = 0.96 for Tmin).

That is just «global» SST with hadcrut Tmax and Tmin.

Most of the USHCN readings of Tmin and Tmax are only good to the nearest 1.00 deg F with a min - max thermometers.
