Modeling and assessing climatic trends
Climate studies often fit linear trends to data. In many cases simplifying assumptions such as independent errors and constant variance are used. We review a variety of approaches to estimating linear trends, and illustrate with US temperature data how oversimplified assumptions may lead to false significance. We outline a variety of methods to fit nonlinear trend models. Using the Berkeley Ear...
متن کاملTemporal Analysis of Rice Yield and Climatic Trends in Pakistan
Climate in its spatial and temporal inconsistency is one of the chief causes for determining agricultural productivity in a region. Climatic impacts should be kept into mind while developing long term agricultural policies. This study aimed at investigating the change in rice production in Pakistan from 1989-2009 using the GIS techniques and the impacts of climate change on rice production. Pak...
متن کاملAnalysis of wheat yield and climatic trends in Mexico
Wheat yields in Mexico, which represent an important measure of breeding and management progress in developing world wheat production, have increased by 25% over the past two decades. Using a combination of mechanistic and statistical models, we show that much of this increase can be attributed to climatic trends in Northwest states, in particular cooling of growing season nighttime temperature...
متن کاملA reversal of climatic trends in the North Atlantic
Short linear trends can be sensitive to the chosen start and end points. An obvious 8 question is to what extent is the observed cooling over the North Atlantic over the 20059 2014 period sensitive to inter-annual variability, especially the anomalous winter of the 1
متن کاملClimatic elements, discharge and groundwater trends over time using Mann-Kendall Test in the Mighan Sub-basin of Arak
This study was an analytical research across 84 meteorological stations, performed in the Mighan sub-basin over a fifty-year study period (1961–2011).This research seeks to answer the basic question of how declining streamflow, increasing temperatures, and fluctuation in precipitation have impacted water resource allocation in the Mighan sub-basin. The research method is analytical based on Man...
